kirby amiibo
the big wool yoshi amiibo
Yeah I looked at the wooly yoshi amiibo since I have wooly world I might get it but it's a bit expensive
The kirby one's cool too but it depends if its the smash 4 one or not because I'm thinking of getting kirby rainbow curse and I could use it on that if it has amiibo functions
