Oh boy, this topic is for me, haha.
I have 135 amiibo right now. Everything in the Smash, Mario, Animal Crossing, Kirby, and Zelda series, plus: Metroid 2-pack, Mega Yarn Yoshi, Pikmin, original Splatoon 3-pack, Chibi-Robo, Shovel Knight, and the 4 Skylanders Superchargers hybrid amiibo. Oh, and the Super Mario Cereal!
I also have the Shovel Knight 3-pack and Ridley, Inkling, and Wolf pre-ordered.
I'm just excited to add to my Smash collection, it took a LOT of work to get all of those. I can't wait to get returning Smash characters like Snake.
