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
On April 1, 2015, Nintendo announced in a Nintendo Direct that 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 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 + 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). 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.

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!"
