Power Egg

"Though slick with slime, I keep my grip. The chill seeps through my gift from you. I mustn't let this cargo slip."

- Agent 8 on the Power Egg mem cake

Power Eggs are a type of collectible currency in the Splatoon series. They appear in single-player mode, Octo Valley, in Octo Canyon and Salmon Run in, and in Return of the Mammalians and Salmon Run Next Wave in. They also appear in the Octo Expansion, being exchanged for CQ Points.

Description
Power Eggs are small, orange orbs that appear similar to fish eggs. Free-floating Power Eggs can be collected by directly touching them or hitting them with ink. When inked or touched, they will fly towards the player and disappear on contact.

In addition to their usage in gameplay, they are universally used as an energy source, with the New Squidbeak Splatoon, Octarians, Salmonids, and Deepsea Metro all making use of them to some degree. It is likely that the ultimate origin of Power Eggs lies with Salmonids, as the Japanese name for Power Eggs directly translates to 'salmon roe'. Additionally, the Salmonids have a standing trade agreement with Octarians, receiving various technology in exchange for supplying the Octarians with energy to operate their machines in the form of Power Eggs.

Power Egg pack
In single-player modes, Power Eggs can often be found in the form of larger packs based on caviar tins, with a label including the Earthworks logo on the top, foil seals, and a translucent body.

In Octo Canyon, Power Egg packs are worth 10 eggs, while in the Octo Expansion, they are worth 25 eggs. In, they are worth 100 eggs when found from a loot anchor, while in levels they are worth 25.

Splatoon
Power Eggs can be found in all Octo Valley missions, usually placed in a way to show where the player should go to progress. Although they are often found in the open, they may also be hidden in crates, balloons, or Octarians. Power Eggs can be used to upgrade the Hero Shot, ink tank, and Splat Bombs, as well as unlock and upgrade the Burst Bomb and Seeker sub weapons. Power Eggs do not have any use in multiplayer modes.

Upgrades
Power Eggs can be spent to upgrade the player's Hero Equipment. Upgrading the gear also changes the color of the lights on it.

Upgrading the Hero Shot increases its rate of fire while upgrading the Ink Tank increases its capacity and upgrading the bombs increases their blast radius.

Any upgrades purchased do not affect any of the amiibo challenges.

Splatoon 2
Power Eggs, retaining their appearance from, are found in single-player campaign, as well as in Salmon Run, and are collectible in the same manner as in Splatoon.

Octo Canyon
Power Eggs function the same way as in Splatoon, their main usage being upgrading the player's Hero Shot and ink tank, unlocking Curling Bombs and Autobombs, as well as upgrading the other Hero Weapons that Sheldon makes available at the Ammo Knights Enhancifier.

Once everything is unlocked and upgraded, they can also be traded in for food tickets that can be used at the Crust Bucket.

Salmon Run
Power Eggs are obtained when splatting any type of Salmonid, including Bosses, with each player's total number of Power Eggs received during the shift shown at the end. Power Eggs collected during shifts do not transfer over to Octo Canyon, though they will be added to the player's Grizzco Point Card for rewards, with every 200 Power Eggs having equal value to one Golden Egg.

Octo Expansion
Power Eggs are obtained just as in Octo Canyon and Octo Valley. When collected, however, the player immediately receives CQ Points, which are then stored on the CQ-80. CQ Points can also be gathered by clearing tests and unlocking new lines, among other methods. CQ Points are required when entering or retrying tests. Similar to their use in Octo Canyon, excess CQ Points may be redeemed for multiplayer rewards at the vending machine unlocked after completion of the Expansion.

Return of the Mammalians
In, Power Eggs are the main currency in Return of the Mammalians. They can be obtained in the missions by splatting enemies or collecting directly, as well as clearing the missions themselves, but they are no longer used to upgrade Hero Gear this time, as Sardinium and Upgrade Points are used instead. They are mainly used to clear the Fuzzy Ooze, and some missions (denoted by silver kettles in the overworld) also require a payment of Power Eggs to attempt, as in the Octo Expansion.

Similar to Octo Canyon and the Octo Expansion, excess Power Eggs accumulated after the player has already eliminated all Fuzzy Ooze can be paid into the Shel-drone once per real-life day, providing them with various multiplayer rewards.

Salmon Run Next Wave
Like in Splatoon 2, Power Eggs are obtained by splatting Salmonids in Salmon Run Next Wave in Splatoon 3. They are once again completely separate from the Power Egg count in single-player and only serve to increase the player's earned Grizzco points.
