Whimsicott appears in Super Smash Bros. for Nintendo 3DS on the Unova Pokémon League stage as a stage Pokémon.
Ever found a white ball of fluff you couldn't quite explain? That was likely the work of of a Whimsicott. Slipping through the tiniest of cracks like the wind, they like to move furiniture around and leave little fluff balls all over the place. Though they look like sheep, they're actually grass types, and their fluff is more like cotton than wool.
