Paper Petey Piranha

Paper Petey Piranha is the paper counterpart of Petey Piranha who appears in Mario & Luigi: Paper Jam as the second boss of Sunbeam Plains. He, like all of the paper characters, came out of the book containing the Paper Mario universe at the beginning of the game.

He is the game's fourth normal boss, and is encountered by Mario, Luigi and Paper Mario chasing a green Toad in Sunbeam Plains. By the time Paper Petey spots the trio, he has caught this green Toad, and after a long monologue by the Toad, he is thrown away by Paper Petey, who then proceeds to battle the trio. During battle, he begins by stealing Paper Mario's Copy Block by sucking in air in order to create copies of himself. The group have to find out which copy is the original one by attacking the stack of Paper Petey Piranhas until they find the one that takes damage while knocked-out on the ground. Paper Petey will occasionally shuffle his copies to try to trick them into attacking the wrong one; if left alone, the real one will occasionally lift its head up. After a few turns, the grounded copies will regenerate their health points and will be reshuffled into the stack of Paper Peteys.

Paper Petey Piranha attacks by charging into the trio using his copies, which they must counter with their Hammers, and by having two of his copies fly into the air, before slamming onto the ground, creating a sequence of two shockwaves that Mario, Luigi and Paper Mario must avoid by jumping over them at the correct time. Once half of his health has been drained, Paper Petey Piranha will become enraged and will begin to initiate a chase where his copies will fly ahead of Mario or Luigi in a sequence and fold up on the ground, which the player must memorize. As the copies are sent out, some will be spaced out and some will be grouped closely together; the Bros. must jump over the copies in the correct order to avoid damage, and grab onto Paper Mario's paper airplane form if the copies are grouped together. The trio eventually defeat him and press onwards into the Gloomy Woods.

In Super Smash Bros. Ultimate, Paper Petey Piranha is mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant.
