When this Final Smash is used, Piranha Plant summons Petey Piranha. He acts in a similar manner to his appearance in The Subspace Emissary, jumping around and capturing opponents in the cages he holds. Each cage can hold one opponent. Then, Petey shoots flames from his mouth to the caged opponents and slams them out of his cages before he disappears.
