Swirlix is a Poké Ball Pokémon that when summoned, uses Cotton Spore to slow opponents nearby.
Swirlix, a Fairy-type Pokémon, has a serious sweet tooth. However, all those sweets make its fur really sticky. If you trade a Swirlix while it holds Whipped Dream, it'll evolve into a Slurpuff. In Smash Bros., Swirlix likes to use Cotton Spore. Getting hit by this attack will seriously slow you down.
