Super Mario Galaxy 2 Electrogoomba Gashapon Mini Figure
They are very common aliens in most galaxies, and bear resemblances to Goombas and Octopus, both of which contribute to the name. Like Shroobs, they are an alien species with a mushroom-like physique. Unlike in the first game, they won't headbutt Mario, but rather, they will spit rocks at Mario just like Octoroks.
