Piranha Plant (Paper Mario: The Thousand-Year Door)
From the Super Mario Wiki
Piranha Plants are enemies found in Paper Mario: The Thousand-Year Door. They are the strongest of all Piranha Plants and like to live in pipes, as indicated in the Tattle Log, despite the fact that no Piranha Plants in the game appear in pipes (though this more likely references the regular Piranha Plants from the Super Mario series). They have the second-highest statistical attack power in the game, exceeded only by an Amazy Dayzee, which is 20. It also has absurdly high HP, only being beaten out by a handful of non-bosses, such as Dark Craws and Dark Koopatrols.
Piranha Plants are rare in Paper Mario: The Thousand-Year Door, found only in the Pit of 100 Trials in floors 81-89.
