Amiibo

amiibo are figurines produced by Nintendo that are equipped with Near-Field Communication technology and can be used in a variety of Wii U and Nintendo 3DS games, including Splatoon and Splatoon 2.

In Splatoon
On April 1, 2015, Nintendo announced in a Nintendo Direct that Splatoon would be receiving three different amiibo on May 29, 2015. These amiibo, when scanned in Inkopolis Plaza, unlock twenty different challenges with five unlockable boss challenges in Octo Valley and new exclusive gear to wear into battle. The three amiibo that have been announced are the Inkling Girl amiibo, the Inkling Boy amiibo, and the Inkling Squid amiibo with the Squid only available as part of the three-pack in North America, and in Europe exclusively in the Splatoon + Inkling Squid amiibo bundle.

Over a year after, a second wave of figures was announced, including the Squid Sisters, Callie and Marie, and three reskins of the amiibo from the previous wave.

Gameplay
The amiibo case is located at the southeastern corner of Inkopolis and it appears as the packaging amiibo traditionally come in. When scanning an amiibo (if the amiibo is registered) a flurry of paint circles the inside as the corresponding amiibo forms inside of it. The character introduces themselves and lays down guidelines for their challenges.

Each Wave 1 amiibo features twenty challenges if the single-player mode, Octo Valley, has been completed. The first challenge gives the player six hundred cash as a reward, with the reward increasing by one hundred more cash for each next challenge (i.e. one mission reward is 1000 cash, while the next mission reward is 1100 cash). Each challenge can be completed again, though for only a reward of 100 cash. When three challenges in the same row are completed, the fourth challenge for that set is unlocked, being the boss for its corresponding area in Octo Valley. As opposed to a monetary reward, the boss challenges provide three pieces of gear for the first three bosses, a minigame for the fourth, and a weapon blueprint for the final boss.

The Squid Sisters amiibo allow the user to view concerts in the plaza, similar to a Splatfest. The three reskins have the same behavior as their original counterparts. The challenge tree is shared between the original and reskinned amiibo.

Inkling Girl
"Dude! Lemme tell you I am SO glad you called me! I'm pickin' up a fresh vibe from you. Tell me...are you a fan of charger weapons? Cuz that's my kinda thing—making up challenges where you gotta use chargers! Are you game? Come to think of it...you've been pokin' around down in Octo Valley, yeah? Yup, I saw you in that rad outfit, fighting those...things. It looked super fun! But you know what would be even radder? If you used a charger weapon! That's my challenge to you. Clear missions with a charger, and I'll hook ya up!"

- Inkling Girl

The Inkling Girl amiibo was released on May 29, 2015 alongside Splatoon. It can be used to unlock 20 Charger challenges in Octo Valley and rewards the player with an exclusive costume piece for every four challenges completed. After completing all challenges, the player will complete the set and receive the exclusive School Gear along with the Squidball minigame and the Hero Charger Replica blueprints. It can be purchased individually or in a pack of three with the Inkling Boy and Inkling Squid amiibo in North America.

The original Inkling Girl amiibo is a light-skinned Inkling with orange tentacles and orange eyes. She wears the Fake Contacts, White Tee, and Pink Trainers and carries the Splattershot. She appears to be based on the Inkling most commonly used to advertise the game, such as on the front cover and for commercials, along with the default girl Inkling.

The recolored Inkling Girl's skin color remains unchanged, but her tentacles are lime green and her eyes are magenta. She wears the Fake Contacts, the Black Tee, and the Black Trainers and carries the Tentatek Splattershot.

Inkling Boy
"Sup, playa?! Thanks a ton for callin' me up! I heard you've been makin' waves around the city. And I've got an inkling that you're the type of Inkling who's up for a challenge. Wanna give one of my roller challenges a go? I heard you've been doing work in Octo Valley. Wearin' that crazy getup, wreckin' Octobros and junk! That's when I knew for sure that you've got what it takes to try my challenges. All you gotta do is beat those same missions using a roller weapon! So are you game? I've got some dope rewards lined up if you can pull it off!"

"Why, hello there, friendo! Thank you kindly for summoning me here. I can see you're just itching for some way to test your skills. Well, I've been thinking up some challenges that might float your boat! What do you say? Think you're up to the task? By the by, I hear you've been making quite a splash over in Octo Valley. In fact, I saw you at it! Wearing outlandish gear and fighting odd creatures! I think that proves you have what it takes to attempt my challenges. What do you have to lose? I have some nice rewards for you if you win!"

Challenges
The Inkling Squid amiibo allows players to complete specific Octo Valley missions in two ways: some can be completed as a Kraken with limited time, and others must be completed with limited ink. In the Kraken Challenges, the player is given the ability to turn into a Kraken instead of a Squid for the entirety of the level. In limited ink challenges, the player is given three or four full Ink Tanks to complete the level, but ink cannot be replenished. The challenges are as follows:

Squid Sisters
Amiibo figurines of Callie and Marie were released on July 8th, 2016. They can be used to unlock exclusive in-game Squid Sisters concerts, including two exclusive solo songs; one for each sister. Using either of the Squid Sisters causes the Plaza to take on its appearance during a Splatfest, and the player will be colored after and wearing a Splatfest Tee for whichever Squid Sister was used. During the concert, no buildings can be entered, nor can Judd be talked to.

The Squid Sisters can perform the following songs, each with its' own dance routine:
 * Ink Me Up (Splatfest Battle)
 * Now or Never! (Splatfest Battle - 1 Minute Remaining!)
 * City of Color (Splatfest Plaza)
 * Maritime Memory (Credits Sequence)
 * Calamari Inkantation (Vs. DJ Octavio - Final Phase)
 * Bomb Rush Blush (Callie's solo; can only be chosen with Callie amiibo)
 * Tide Goes Out (Marie's solo; can only be chosen with Marie amiibo)

amiibo tap: Nintendo's Greatest Bits
amiibo tap: Nintendo's Greatest Bits, known in Europe and Australia as amiibo Touch & Play: Nintendo Classics Highlights, is a downloadable application for Wii U that allows amiibo owners to try out classic NES and SNES games. All amiibo figures work with the application.

Animal Crossing: New Leaf
As part of an update for Animal Crossing: New Leaf, amiibo compatibility was added, which includes Splatoon amiibo as well. At a certain point, the player will find a magic lamp that will allow them to summon Wisp once a day. When summoning Wisp, the player can tap a compatible amiibo for him to take the form of the villager it is associated with. The player can either ask for an item or for the real villager to show up at the new Campground area. There, the villager will be waiting for the player in an RV. Inside, the player can ask the villager to move into their town, as well as order furniture using MEOW coupons.

Tapping the Callie amiibo will summon Cece the Squirrel. The Marie amiibo summons Viché the Squirrel. Both variants of the Inkling Boy, Girl, and Squid amiibo summon Inkwell the Octopus. Each villager comes with their own Splatoon themed items to order as well.

In Captain Toad: Treasure Tracker, the Splatoon amiibo figures can be used for a 1-UP Mushroom. Most of the other amiibo figures can be used for this as well, however.

In the Western version of Nintendo Presents: New Style Boutique 2 - Fashion Forward (released in North America as Style Savvy: Fashion Forward), players are able to scan the Inkling Girl amiibo to unlock a pair of leggings inspired by Splatoon.

When the request is completed, the player will be rewarded with those leggings.

Pokkén Tournament
The Splatoon amiibo figures can be tapped once a day in Pokkén Tournament for an avatar costume item, a title, or a Poké Gold bonus. Up to 5 amiibo rewards can be claimed per day. Most of the other amiibo figures can be used for this as well, however.
