Goombule

Goombules are a type of cell-based Goombas found inside the Trash Pit and Pump Works areas of Bowser in Mario & Luigi: Bowser's Inside Story. Goombules have a dark pink egg-yolk shaped body with an orange nucleus in the center. To attack Mario or Luigi, a Goombule will either charge down the bros. or try to roll into them. When a Goombule approaches to attack, it will pause in the center of the battlefield and lean backwards if it is targeting Mario; if it leans forward it is after Luigi. Both Goombule attacks are avoided by jumping, and with the right timing the jump can also be used to counterattack. When Mario and Luigi practice one of their Attack Parts moves, the targets will be Goombules. They are the first and weakest enemies Mario and Luigi encounter as a team, and ultimately the weakest enemies in the game. The name Goombule is a pun on "Goomba" and "globule".
