Prickly Piranha Plant

The Prickly Piranha Plant, also known as the Spiky Piranha Plant , is a variety of Spiny Piranha Plant that appears in Super Mario Galaxy 2.

Super Mario Galaxy 2
The Prickly Piranha Plant attacks in the same way as its purple counterpart: slamming its head onto the ground. However, unlike the purple counterpart, the player cannot jump on it due to its spikes and must use the nearby rubbery bulb to defeat it by hitting its head when it is down on the ground. This enemy only appears in Sky Station Galaxy during the Storming the Sky Fleet mission, where it holds a key to the locked up Power Star nearby and must be defeated.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, Piranha Plant becomes a small Prickly Piranha Plant for its side smash attack. In Palutena's Temple, Prickly Piranha Plants (just called Prickly Piranhas) are mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant.
