Return of the Mammalians is a single-player game mode in Splatoon 3. It involves the player donning a Hero Suit and venturing into the Crater to defeat the Octarian army (which is now covered in hair), soon ending up in Alterna.

Story

An Inkling or Octoling and their buddy Smallfry arrive in Splatsville, where Shiver, Frye, and Big Man of Deep Cut report in a special Anarchy Splatcast broadcast that the Great Zapfish that powers the city has gone missing. The Inkling or Octoling goes through a manhole leading to the Crater, where they meet Craig Cuttlefish. He recruits them as the new Agent 3 of the New Squidbeak Splatoon and gives them a Hero Suit, enlisting them to rescue the Great Zapfish from the Octarians, who stole it twice before.

Agent 3 progresses through the Crater, rescuing Zapfish from the Octarians and clearing away Fuzzy Ooze by powering up Smallfry with Power Eggs. Along the way, Cuttlefish notices that the Octarians are now fuzzy and tries to contact Agent 1 and Agent 2 to provide backup. DJ Octavio intervenes in the communication, but Cuttlefish dismisses it as his radio being broken.

When Agent 3 reaches the center of the Crater, DJ Octavio appears in his battle mech, the Octobot King L3.Gs, and accuses Cuttlefish of being behind the disappearance of his Octarian troops. After Agent 3 defeats him in battle, Cuttlefish taunts him for being easy to defeat, as though he was not using the Great Zapfish's power. However, Octavio then reveals that he did not steal the Great Zapfish this time, to Cuttlefish's shock. Suddenly, the ground beneath them collapses as Fuzzy Ooze flows out. A tentacle-shaped piece of Fuzzy Ooze takes Cuttlefish away from Agent 3, who loses their Hero Suit and Power Eggs in the fall. Meanwhile, Deep Cut watches from above.

Agent 3 waking up in Alterna next to Smallfry.

Agent 3 wakes up in the mysterious location of Alterna, where they are greeted by the New Squidbeak Splatoon, comprised of the Squid Sisters (Agents 1 and 2) and the Captain (the former Agent 3). They explain to Agent 3 that Alterna, which is also full of Fuzzy Ooze, consists of six sites, as well as a large rocket. Three of the sites are emitting strong signals that they suspect come from a tracking device they placed on Cuttlefish. Agent 3 is tasked with investigating these three areas in order to find Cuttlefish.

Agent 3 progresses through Alterna, continuing to remove Fuzzy Ooze along the way. In order to get enough Power Eggs to do this, they complete missions set by an AI known as O.R.C.A.

As Agent 3 reaches the end of the first site, Future Utopia Island, Deep Cut suddenly appears. The three of them introduce themselves, revealing that they are actually bandits and declaring that the Splatlands are their turf and all the treasure in Alterna belongs to them, before departing.

Agent 3 visits each of the three locations that are emitting signals. Each time, they encounter one of the three members of Deep Cut and defeat them in battle, only to find that the signal was coming from the treasure they were guarding, which Agent 3 takes. After the first treasure is collected, Cuttlefish manages to make contact with Agents 1 and 2 and reveals that he is locked in a dark room. After the second treasure is collected, he briefly makes contact again, until he is confronted by his unseen captor, Mr. Grizz. After the third treasure is collected, Cuttlefish makes contact again and deduces from his aching knee that he is high up before Mr. Grizz cuts him off.

Agents 1 and 2 deduce that Cuttlefish is in the rocket, which they cannot reach due to the Fuzzy Ooze surrounding it. They assemble the treasures into a large tool, which the Captain uses to remove the Fuzzy Ooze, allowing the team to proceed to the Alterna Space Center, though the Captain ends up hurt from using the tool. Soon after this, Deep Cut appears again, trying to take back the treasure, but to their surprise, Agent 2 agrees to let them have it. Regretting their hostility, Deep Cut apologize and ask Agent 2 to be their boss, who reluctantly accepts.

Agent 3 makes their way up the rocket. On their way, they overhear Mr. Grizz talking to Cuttlefish about his plans to use Golden Eggs (collected by his unwitting employees at Grizzco Industries) to "restore the balance of the world". Agent 1 also asks Deep Cut about their reason for hunting treasures, and they explain that they sell the treasure to help those in need in Splatsville while leaving little for themselves, which makes Agents 1 and 2 respect them. Agent 3 also passes by the Great Zapfish trapped in a container in the rocket.

As Agent 3 nears the top of the rocket, they overhear Mr. Grizz attacking Cuttlefish, claiming his brain contains the "beautiful essence" he needs. At the top, the New Squidbeak Splatoon find Cuttlefish dried up and lifeless as a result of being dehydrated by Mr. Grizz, who finally confronts them, revealing him to be a grizzly bear. He escapes on the rocket as it takes off, announcing his intention to spread Fuzzy Ooze all over the planet and bring forth a new era of mammalian dominance.

The Captain sheds a tear on Cuttlefish's body, which moistens him enough to awaken him, albeit still with his dried-up appearance. Deep Cut helps Agent 3 and Smallfry reach the rocket in space, where they fight Mr. Grizz. After having the Fuzzballs on his body splatted, Mr. Grizz knocks Agent 3 and Smallfry off of the rocket as he absorbs the Fuzzy Ooze and plans to unleash it on Earth himself. However, DJ Octavio flies in with his Octobot King to save them, wanting to help stop Mr. Grizz's plan. He, the Squid Sisters, and Deep Cut then perform Calamari Inkantation 3MIX together, and Smallfry becomes Hugefry. In the final battle, Hugefry fights Mr. Grizz as DJ Octavio and Agent 3 vacuum the Fuzzballs on his body. After vacuuming all of the Fuzzballs, they fire the fuzz back at him, defeating him in a large explosion. Smallfry returns to normal and joins DJ Octavio and Agent 3 as they return to Earth.

In an Anarchy Splatcast broadcast, Deep Cut reports that the Great Zapfish has returned to Splatsville and that the Squid Sisters have released a new single, Wave Goodbye. After realizing that Agents 1 and 2 are in fact the Squid Sisters, they set aside their disdain for the Squid Sisters and play the song. When Agent 3 returns to Alterna, they are congratulated by Agents 1 and 2, Cuttlefish, and the Captain for saving the world.

Gameplay

Mechanics

Compared to the Hero Mode of the previous two games, Return of the Mammalians has a less linear progression similar to the Octo Expansion. When the player enters a mission, O.R.C.A. explains the premise of the level with dialogue and prompts the player to select one of the sets of weapons available. Different sets of weapons may have different Power Eggs rewards. Some missions also cost Power Eggs to play, and/or have special conditions that will cause the player to get splatted if they fail.

The areas in this mode are covered in Fuzzy Ooze, which serves as the obstacle blocking the path to other areas, rather than having the missions locked themselves. The player needs to use the Power Eggs they collect from the missions to clear them and progress.

The map screen in each of the sites tracks how many of each type of item the player has found on the overworld (loot anchors that contain decorations, golden records, Sardinium, and Sunken Scrolls). The map highlights areas with unobtained items to find in green, labeled as Areas of Interest, whereas it marks areas which the player has not been to yet with black striped squares labeled Parts Unknown. If the player fully collects all items in a site and goes to every possible part of the map so that there are no longer any black squares, the site becomes marked as "Surveyed". Marie will award the player with a piece of the map of Alterna as a sticker if they survey that site.

Fully surveying all sites causes a Shel-drone to appear. Each day the player can charge this drone by using 999 power eggs. The following day, the drone will send an item to the lobby terminal. These items include cash, ability chunks, and meal tickets, as well as decorations that can only be found in Alterna. This is currently the only way to get duplicates of these decorations. If the Shel-drone does not appear after the player surveys every area, they will need to go back to Splatsville, and then Alterna again.

Enemies

Regular enemies

This table is sorted by order of appearance. Enemies marked with * are newly introduced in Splatoon 3.

Image Name Description Debut
Fuzzy Blobby Octotrooper Octotroopers that ride a different machine resembling a gumball machine. They act and look almost identically to their regular versions but shoot a duo of shots that bounce along the ground. These can deal a lot of damage in numbers but are also susceptible to gravity. No. 1 Octarians in the Crater? YIKES!
Fuzzy Octocopter Flying enemies propelled by their helmets. They hover above the ground and shoot at Agent 3 on sight, but their projectiles and general flying speed are slow, like Octotroopers. No. 3 Boxes Locked! Keys, Please!
Fuzzy Octotrooper The basic grunts of the Octarian army, Octotroopers stand on small machines that allow them to shoot single, very slow ink globules. They have very little health and mobility and so are easily defeated, but may pose a threat in numbers. No. 4 What Are They? Can We Stop Them?!
Fuzzy Shielded Octotrooper Octotroopers with shields in front of their machines. The shield can be destroyed after taking a lot of damage, but their exposed backsides are their weak spots, easily hit after being distracted, such as by Smallfry. Also appears in Octodiver and Twintacle Octotrooper forms. 0101 Get to Know Alterna, Your Only Choice
Squee-G Although incapable of dealing damage, these very rare small robots serve as nuisances, attaching to walls and automatically sucking up Agent 3's ink. They can sometimes carry items and slow down upon being attacked. 0101 Get to Know Alterna, Your Only Choice
Octopod Small metallic creatures that run around in sneakers. Octopods jump to attention upon seeing the player. Upon reaching them, they explode in Octarian ink, dealing some damage. They can be attacked to be defused. They appear to be Octorpedoes on legs. 0102 Octopods at Rest Tend to FLIP OUT!
Oversized Octopod* Giant Octopods that move and attack in a similar way to their smaller counterparts. However, they are slower but require much more damage to detonate, having a much larger blast radius as well. 0102 Octopods at Rest Tend to FLIP OUT!
Fuzzy Octosniper Elite enemies that shoot long, thin, and very powerful shots of ink, similar to chargers, while stationed on immobile platforms. Like charger users, they have an extremely long line of sight but are mostly incapable of close-quarters fighting, while their shots require some time to charge and are marked with a laser line. 0104 Doors, Doors, Doors! And More! (Doors)
Fuzzy Octocommander Large stationary enemies that are very similar to Octosnipers. They can only rotate in place and use giant splatlings to attack quickly over a large range. However, they take a while to recharge, leaving them wide open. 0104 Doors, Doors, Doors! And More! (Doors)
Fuzzy Rocket Octocopter Darker versions of Octocopters that have thrusters attached to their helmets. Although they are no stronger than normal, they can quickly dodge left and right, making them a nuisance to defeat. 0109 The String's the Thing
Fuzzy Amped Octostamp* Stronger Octostamps that are recognizable by their headphones. They have a cover over their weak point, requiring more damage to break, and send out a damaging shockwave on contact with the ground similar to the Wave Breaker. 0110 Deadly Dance Hall—Jump, Jump!
Fuzzy Twintacle Octotrooper Stronger Octotroopers with two tentacles. These enemies have better mobility than the normal Octotrooper and greater ink-firing capability, similar to a splatling, but are still easy targets. 0201 Twirling, Swirling, Whirling
Fuzzy Octomissile Little explosive missiles with a tentacle in the middle. They spawn infinitely and burst with ink on contact, but can be defeated simply by being attacked. 0205 Tread Heavily
Fuzzy Octozeppelin Giant airships themed after Octarians with a single tentacle sticking out the top. They spawn infinitely, using their propellers to spray ink behind them, and are invulnerable apart from their tentacle. 0302 They Said We'd Have Flying Cars, and We Do! Kinda!
Octowasher Indestructible spinning torrents of ink that appear as damaging barriers. They deal fatal damage on contact and block shots, meaning they can only be avoided. 0304 Try Curling! Alterna's 11th Most Popular Athleisure Activity!
Fuzzy Octohopper* Bouncing Octotroopers that follow Agent 3 on sight. Although they are as weak as regular Octotroopers, they are persistent and attack with slosher-like ink flings which deal a lot of damage. 0402 Octohoppers Don't Have a Sense of Humor (and They Hate Puns)!
Fuzzy Octoballer Inky bowling balls populated by Octotroopers that spawn infinitely and leave a trail of ink behind them. They can only be destroyed by attacking the Octotrooper as normal. 0403 Let's Put a Pin in That
Fuzzy Octodisco* Flying spherical Octarians that look similar to disco balls. Instead of attacking Agent 3, they hover over other enemies and form a shield like the Big Bubbler. In this state, they can only be attacked from above, but the shield breaks if the enemy inside is defeated. 0407 Charge Now, Splat Later
Fuzzy Octoling Octarian variants of Inklings that act as elite forces en masse and can utilize a wide variety of main, sub, and special weapons. Dark-haired Elite Octolings are much harder to defeat and act similarly to human opponents in multiplayer modes. 0411 Stamp 'Em Out
Fuzzy Octostamp Cuboid, machine-like creatures with inky faces. Although they are not fast, they can leap into the air and face-plant the ground, dealing fatal damage. They can only be defeated from behind, which is exposed by their method of attack. 0411 Stamp 'Em Out
Fuzzy Rocket Twintacle Octotrooper Noticeably darker Twintacle Octotroopers. They have the same capabilities as normal Twintacle Octotroopers but with jet thrusters on their machines, making them capable of fast dodges. 0501 Trouble Round Every Corner
Flooder Huge machines on stilts that rain down Octarian ink from under them and move in set patterns. They charge at Agent 3 on sight and can defeat them instantly if not distracted by Smallfry, but their tops also act as platforms that can hold items and other mechanics. Big Flooders are even taller and harder to scale. 0505 A Compulsive Collector's Paradise
Fuzzy Octodiver Octotroopers wearing snorkels, which allow them to breathe under their ink. They pop out without warning to attack and can dive to hide like Agent 3. Also appears in Shielded Octotrooper and Twintacle Octotrooper forms. 0508 Making Waves with Splashdowns
Fuzzy Octobomber Large flying Octarians similar to improved Octocopters. They hover around and shoot Splat Bombs out of their helmets which detonate fatally one second after landing. However, they are large, slow, and unwieldy, making them obvious targets. 0509 Low Viz, High Risk
Fuzzy Rocket Octobomber Darker variants of Octobombers that can use the rocket thrusters on their helmets to quickly dodge to the side when being attacked. Their attack pattern has not changed, however. 0509 Low Viz, High Risk
Fuzzy Tentakook Extremely rare little Octarians that hide important items and give chase on sight. They use their ink-powered roller skates to cover their tracks and can drop Splat Bombs behind them. They are very fast and can only be caught by swimming in ink. 0611 Don't Tease with the Keys
Octorpedo Missiles filled with Octarian ink fired by Mr. Grizz. Acting like flying Octopods, they home in on Agent 3 and explode, but can be easily shot down. However, amongst the rest of the boss battle, they can serve as major distractions. Rocket  1 The Ursine Anomaly - #03

Bosses

Image Name Description Debut
DJ Octavio and the Octobot King L3.Gs The leader of the Octarians in his signature machine, now with added legs and new attacks to make up for no longer being powered by the Great Zapfish. Like in previous appearances, Octavio attacks with a variety of fist attacks which must be avoided or shot back to damage him. In later phases, he utilizes Ink Vac and Wave Breaker attacks as well. Crater  Octobot King L3.Gs
Frye and moray eels* The first member of Deep Cut. She rides on the remains of the Octostomp out of range and attacks by shooting dozens of moray eels at Agent 3, which must be avoided or shot back to damage her. When stunned, the player must scale the Octostomp to damage her directly, after which she adds a variety of extra eel attacks to her move set. 02  The Future Stares Back
Shiver and Master Mega* The second member of Deep Cut and her shark, which she rides mostly out of range of attack. Although they can be damaged while circling the arena, it is easiest to attack Master Mega when it charges onto the arena like the Reefslider, at which point Shiver can be attacked directly. In later phases, they jump between ink tornadoes around the arena and attack much faster. 04  The Pursuit of the Precious
Big Man* The third and final member of Deep Cut. He transforms into a shadow and floats around the arena, leaving ink behind. When attacked, the shadow splits into smaller ones which attack with various bomb blasts. The real Big Man shadow is identified through the Squid Sensor, whereas fake ones explode. In later phases, the shadows attack faster and with more bomb types. 06  The Obscurest Chiaroscurist
Mr. Grizz* He is Ursine Anomaly #3 and CEO of Grizzco Industries who has harvested Golden Eggs and stolen the Great Zapfish to return mammals to the world through his Fuzzy Ooze. Agent 3 must dodge his many attacks and clear Fuzzy Ooze with Smallfry to be able to attack Grizz directly, after which he intensifies his attacks. In the second half of the battle, Agent 3 must work with DJ Octavio to use the Octobot King L3.Gs' Ink Vac and absorb and shoot out the Fuzzballs on Grizz's body within 3 minutes and 33 seconds, all while avoiding space debris. Rocket  1 The Ursine Anomaly - #03

Quotes

“ SRL historian here with a pro tip. Want to learn about the weird world of Alterna AND brush up your skills with all kinds of weapons and varied terrain? Check out Story Mode! Just follow the strange old man into the Splatsville sewer to get started. Wow, new sentence.

Another Story Mode tip: most stages allow you to choose from multiple weapon loadouts. So you can sharpen your skills AND take advantage of a weapon's particular strengths to survive. That said, sometimes you'll have nothing to rely on but your wits... and maybe a Zipcaster.

Similarities with Octo Expansion

Return of the Mammalians bears multiple similarities to Octo Expansion. Both stages share their name with a playable game mode within their respective Splatoon games.

Story mode progression

  • The player can choose between different non-Hero weapons.
  • Both modes have a similar interface, a variety of mission conditions and heightened freedom as opposed to the previous two story modes' linear progression.
  • Both modes have a form of currency
    • Return of the Mammalians has Power Eggs.
    • Octo Expansion has CQ Points.
    • Use of in-game currency is required to unlock or attempt missions, progressing the campaign.
  • In Return of the Mammalians, Power Eggs are also used to clear Fuzzy Ooze that blocks the way.
  • Both modes have a key NPC that guides the player throughout an area or splats them if they fail certain objectives (such as running out of ink or time).
  • Both modes are underground, far below the sea level of Earth.

Final stage

In both Octo Expansion and Return of the Mammalians, the player must face a continuous final stage before attempting to face the final boss of each campaign. The start of both stages removes the player's weapons and requires the player to re-equip their gear along the way. Both stages also feature an "unlimited use" section that allows special weapon use without losing special power.

Return of the Mammalians

The final stage in Return of the Mammalians is the Alterna Space Center with the initial Alterna Space Center: Entrance starting the player with no gear.

The section for unlimited special weapon use is The Spirit Lifter: First Class with Zipcaster as the weapon.

Octo Expansion

The final stage in Octo Expansion is Deepsea Metro Escape with the initial areas of Coccyx Phase and Villi Phase starting the player with no gear.

The section for unlimited special weapon use is Diaphragm Phase with Inkjet as the weapon.

Penultimate missions

Both of these sequences feature two songs written by the game's main idol group.

The penultimate mission uses different music for each section: the first plays a modified version of the enemy's theme, and the second plays the idol's theme.

In both final missions, the successful final attack grows so powerful that the attack damages the game UI in some way.

In both final missions, being splatted or running out of time will show an additional cutscene of the world being destroyed before showing the 'Continue?' screen.

Return of the Mammalians

The first mission is The Ursine Anomaly - #03, using Bear with Me as the theme.

The final mission is Return of the Mammalians (mission), using Calamari Inkantation 3MIX as the theme. DJ Octavio's Ink Vac destroys the game UI as the attack power increases.

Octo Expansion

The first mission is the brainwashed Agent 3 using Splattack! (Octo) as the the theme.

The final mission is Turf War (Octo Expansion) using Fly Octo Fly ~ Ebb & Flow (Octo) as the theme. Pearl's Princess Cannon destroys the game UI as the attack power increases.

Changes after completing the mode

After the player completes Return of the Mammalians, the following changes occur:

  • The Great Zapfish can be seen in Splatsville.
  • Li'l Judd starts to wear a headset.
  • Deep Cut in Splatsville and the Squid Sisters in Inkopolis Plaza both have more enthusiastic animations when the player zooms in on them in their studios.
  • The statue used by Mr. Grizz in Grizzco buildings changes from a bear eating a fish to a large fish eating a miniature bear, though his dialogue icon remains the same. The original Mr. Grizz statue appears in Alterna behind the Squid Sisters Camp, and can be interacted with to replay the final Alterna Space Center section or watch the credits again via memories.
  • Cuttlefish, in his dried-up form, joins the Squid Sisters and the Captain at the Squid Sisters Camp, where he can be spoken to.
  • The Spirit Lifter in Alterna is replaced by a near-identical rocket that is blue rather than orange.
  • If the player has fully surveyed all of Alterna by visiting all of the space on the map, the Shel-drone appears on the platform near the Squid Sisters Camp.
  • If the player has completed every level in Alterna, the secret kettle for After Alterna appears at the spot where the player first arrived in Alterna.

Trivia

  • Return of the Mammalians is the first single-player mode in the Splatoon series:
    • to not have "Octo" in its title.
    • to not feature any levels based on multiplayer stages.
    • to not feature multiple levels focused on Octolings, and to not introduce the Octolings via a mini-cutscene.
  • Return of the Mammalians is the only single-player mode in the Splatoon series in which the player can play as either an Inkling or an Octoling, without being restricted to one or the other.
    • Cuttlefish's quotes about Octarians and squid references do not change when the player is an Octoling.
  • Agent 3 has two styles of the Hero Suit. A post on Nintendo's official website hinted that they are "each suited to different situations".[4]
    • In-game, the torn down version is a "standard" form while the other is part of the upgradable Hero set.
  • Many mysterious sounds can be heard in Alterna, but are hard to hear and are distorted. This ambient noise includes announcement messages sent over a loudspeaker system to the Alterna Space Center, with various notification sounds and human speech in English reporting on the status of the rocket launch.
  • The Booyah Bomb and Tacticooler special weapons are the only ones in the game that were available at the game's launch to not appear in any way in Return of the Mammalians. Big Bubbler, while not available for use by the player, is used by Octolings in the final section of After Alterna.
  • Before version 1.1.1, if the player closed the game or entered sleep mode during Deep Cut's news broadcast directly after beating the final boss, they would be forced to replay the entire final section due to a glitch.
  • As level progression in Return of the Mammalians is linked to collecting Power Eggs rather than completing levels, the ending can be reached by completing a minimum of 15 levels (the five Crater levels, the three Deep Cut bosses, and the seven stages in the final Alterna Space Center sequence). This is the fewest required levels of any single-player mode in the series, with one fewer than the Octo Expansion.
