Fire Stalking Piranha Plant
From the Super Mario Wiki
Fire Stalking Piranha Plants (sometimes abbreviated as Fire Stalking Piranha Pl.) are fire-breathing variants of Stalking Piranha Plants that first appear in Mario & Luigi: Superstar Saga + Bowser's Minions. They appear as enemies and allies in the Minion Quest: The Search for Bowser mode, and are first encountered in the level Hunger Pains. They are Ranged troopers, and attack by spitting fireballs at enemies. Their special attack is Spitfire Fury, which allows them to spit multiple fireballs at a targeted enemy. They are strong against flammable enemies such as Pokeys and Fuzzbushes.
Fire Stalking Piranha Plants also reappear as allies in the Bowser Jr.'s Journey mode in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.
