Piranha Pest

Piranha Pests are Piranha Plants species that appear in two games: Yoshi's Story and Mario & Luigi: Partners in Time.

Yoshi's Story
In Yoshi's Story, Piranha Pests simply resemble the bud of a Piranha Plant with a propeller instead of a stem or stalk. They have tongues almost as long as a Yoshi's, but instead of making eggs, they attempt to swallow the Yoshi and shrink it temporarily. They can only be defeated with a Yoshi's egg.

Piranha Pests are an exotic variation of Piranha Plant indigenous to P.4-3, Piranha Grove. They appear to weave in and out of the many large Piranha Plants in search of food.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, Petey Piranha can spit out Piranha Pests (referred to in the Player's Guide as a "plant-pendulum" ). These plants use their long tongues to swing on a block, trying to slam into Mario or Luigi. If they are hit with a hammer a few times, they will be defeated.

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