Fire Nipper Plant

Fire Nipper Plants, also known as Fiery Walking Piranhas or Walking Ptooies , are rare fire-breathing versions of Nipper Plants.

Super Mario Bros. 3
In Super Mario Bros. 3, only one appears in the entire game, near the end of World 7-8. Once it spots Mario, it attacks him by spitting fireballs similar to Venus Fire Traps, though a Fiery Walking Piranha can shoot up to four fireballs at once.

Mario & Luigi: Dream Team
These enemies, now referred to as "Nipper Plants", appear as background enemies in Mario & Luigi: Dream Team. In battle, a Piranha Plant may spit out Nipper Spores into the background, each one instantly becoming a Nipper Plant. Once created, they shoot fireballs at Mario and Luigi individually, which they must deflect with his hammer to avoid taking damage and to also randomly hit the Piranha Plants in the process.

Occasionally, a Piranha Plant will spit a fireball towards the Nipper Plant, who will bounce the fireball about until each Nipper Plant has touched the fireball at some point, where the last Nipper Plant to touch it sends the fireball towards Mario, who must hammer it back at the Piranha Plant who created it to counter-attack and avoid taking damage. The Nipper Plants are defeated when the Piranha Plant that spawned them is defeated.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, these Nipper Plants are mentioned briefly by Viridi in the Japanese Palutena's Guidance dialogue for Piranha Plant. They are not mentioned at all in the English version; however, when set to Simplified Chinese, Traditional Chinese or Korean, its name is subtitled as Fire Nipper Plant in English.

Paper Mario: The Origami King
In Paper Mario: The Origami King, regular Nipper Plants are mentioned to spit fire in the Musée Champignon description for them, although they do not actually spit fire.
