Pestnuts are round plant-like enemies found at Chucklehuck Woods in Mario & Luigi: Superstar Saga. They camouflage themselves as brown Chuckola Fruit before dropping from their trees and attacking anyone who walks under them, though they can also be found rolling around on the ground. Pestnuts are covered in green spikes, making them impossible to jump on unless one of the "Spiny-Killer Jump" badges are worn. They attack by rolling into their target from the front or from behind. The former can be countered with Mario or Luigi's hammer, whereas the latter can be dodged by jumping. After the Pestnut takes enough damage, its spikes fall out, revealing either a Beanie or Gold Beanie underneath. It will then continue to fight as a Beanie.
In Mario & Luigi: Superstar Saga + Bowser's Minions, they are more circular, the spikes are thicker, and the placement of the spikes invokes that of an Urchin, particularly the six spikes around the face. The Chuckola Fruit they camouflage as is now bright orange with yellow "teeth."
