Amiibo

amiibo are figurines produced by Nintendo that are equipped with Near-Field Communication technology and can be used in a variety of games.

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 Hero Mode and new exclusive accessories to wear into battle. The three amiibo that have been announced are the Inkling Boy amiibo, the Inkling Girl amiibo, and the Inkling Squid amiibo with the latter only purchasable exclusively in the three-pack in North America, and in Europe exclusively in the Splatoon + Inkling Squid amiibo bundle.

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 amiibo features twenty challenges if the single-player, 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). 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.

Inkling Boy
The Inkling Boy amiibo was released on May 29, 2015 along with Splatoon. It can be used to unlock 20 Roller challenges in Hero Mode and will provide the player with an exclusive character piece after every four challenges completed. After completing all challenges, the player will complete the set and receive the exclusive Samurai outfit. It can be purchased separately, or in a pack of three with the Inkling Girl amiibo and the Inkling Squid amiibo in North America.
