Pestnut

Pestnuts are small, round, plant-like enemies that are found in Chucklehuck Woods in the game Mario & Luigi: Superstar Saga. They camouflage themselves as brown Chuckola Fruit before dropping from their trees and attacking passersby. Pestnuts are covered in green spikes, making them impossible to Jump on unless the player is wearing any of the "Spiny-Killer Jump" Badges. The spiky creatures can attack by rolling into their target from the front or behind.

A stronger variety of Pestnut with purple spikes can be found on the Seabed of Oho Ocean. After the Pestnut takes enough damage, the spikes fall out, revealing a Beanie or Gold Beanie underneath.
