In case you weren't aware, Fairy-types are strong against Dragon-types in the world of Pokemon, for some reason. Don't bother questioning it - this is a world where water is weak against plants for some reason. But the end result is a big sweet pink puffball like Wigglytuff is a goddamn golden god against a powerhouse dragon like Salamance. Basically...

Do not fuck with Wigglytuff if you're a dragon.
