I don't know if it had anything to do with Splatoon for Nintendo's WiiU winning a Golden Joystick award, but finally after months of being impossible to get and never visible on store shelves, Splatoon amiibos are available!
This three-pack is the only way to get the Squid amiibo. The squid amiibo gets you a set of armor that you gradually unlock parts for as you complete specific challenges. It also gets you the Hero Shot replica weapon for your character, and the Squid Beatz mini-game. In case the title isn't self-explanatory, it's a rhythm-based game. You have to hit either the D-pad or buttons in time with the symbols that appear to one of the music tracks from the game.
Here's the girl amiibo.
The girl amiibo gets you the school uniform, again unlocked in parts by completing exclusive challenges, the Hero Charger Replica weapon, and the minigame Squidball.
Last but not least, the boy amiibo unlocks a set of challenges that allow you to earn a super-cool Samurai outfit, the Hero Roller Replica weapon, and the minigame Squid Racer.
The purpose of the mini-games is to give the player something to do while they're waiting for a match to fill up with players. The new challenges that are unlocked are segments of new single player content done with different weapons and battle conditions than the default single player mode. While I'm still not totally cool with the idea of having to collect plastic toys to unlock in-game content, I at least appreciate that Nintendo made an effort to make these amiibo more available after they had a good idea of how many people are actually playing the game. My guess is that the original wave of these figures went directly to collectors and eBay scalpers and not to people playing the game. Based on my older son's opponents, I would say that more people are actually able to get the extra outfits now.
