Pestnut

Pestnuts are small, round, plant-like enemies found in Chucklehuck Woods in the game Mario & Luigi: Superstar Saga. They are covered in green spikes, making them impossible to Jump on unless one is wearing a special Badge. They can attack by rolling into their target from the front or behind. A stronger variety with purple spikes can be found on the Seabed of Oho Ocean. In both forms, after the Pestnut takes enough damage, the spikes fall out, revealing a Beanie or Gold Beanie underneath. However, in the Oho Ocean variety, the Beanie will merely float up to the surface, eliminating the need to fight it.
