Goombule

Goombules are a type of cell-based Goombas found inside the Trash Pit, and Pump Works, areas of Bowser's Body 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 begin it's attacks, it will go directly to the brother it is using it's charge attack against him, or it will pause in the center of the battlefield and lean forward or backwards if it's using it's roll attack. If it lean backwards, it is targeting Mario; if it leans forward, is that it will attack Luigi. Both attacks of Goombule, are avoided by jumping out the way, and with the right timing, the jump can also be used as a 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".
