Octoomba

The Octoomba appeared in 2007 video game called Super Mario Galaxy. Octoombas, originally referred to as Electrogoombas, are enemies that first appear in Super Mario Galaxy. 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.
