That Sonic amiibo you own isn’t useless just yet, as the upcoming Yoshi’s Woolly World for Wii U will be compatible with it. Using it will let you play as Sonic the Hedgehog Yoshi, who has Sonic’s colours and shoes. He even has green eyes!
Pretty much every amiibo, aside from Pokémon amiibo for some reason, will be compatible with the game. Each of which unlocks a new Yoshi skin based on the character. Even the original Yoshi amiibo for Super Smash Bros. will let you unlock a skin that looks like a more normal, non-yarn Yoshi.
So while you can use quite a few amiibo with various games, so far it’s only been possible to use the Sonic amiibo with the latest Super Smash Bros. However, soon you’ll also be able to use it with Mario Kart 8 as well, as Nintendo is adding compatibility for more amiibo (including Sonic) in an upcoming update.
After this update you’ll be able to unlock a Sonic racing suit and helmet for your Mii by using your Sonic amiibo with the game. Meaning that you can finally race against Mario while pretending that you’re playing as Sonic. This is what fans have been waiting for since Sonic started driving a car in Sonic Drift.
Other new compatible amiibo include Mega Man, Bowser, Toad, Olimar, Rosalina, Villager, Pac-Man, and of course Wario. The update, which also includes a new 200cc mode with appropriately faster gameplay, will be released on April 23rd.
