Octoomba

An Electrogoomba is an enemy who made its first appearance in Super Mario Galaxy. It is an alien, amphibious Goomba that can be found on many galaxies.

Super Mario Galaxy
They are seen in various parts of the game and headbutt Mario when he approaches. In some cases, if Mario destroys some, a secret may be unveiled, as seen on several Airships in the game, where Mario had to eliminate two of them to make a bridge appear. They can easily be squashed. When jumped on, a Coin is always left by them. When a Star Spin is used to defeat them, they leave three star bits.

Super Mario Galaxy 2
Electrogoombas are set to appear in the upcoming Wii game Super Mario Galaxy 2.

Appearance
Electrogoombas are odd-looking Goombas. They have smooth, blue skin with yellow spots, a puckered round mouth (like a Snifit), glowing yellow eyes, and a small antenna on top of their head. Unlike regular Goombas, the have no body. They attack with a headbutt, and only patrol a very small, set area.

Sub-species
One sub-species is a pink color, and is somewhat smarter than the standard one. It attempts to run away from Mario, and will spit rocks at him if he gets too close. Another sub-species of Electrogoomba is gray, and taller and bigger then the other two. It is immobile, but can shoot projectiles at Mario, which include harmless coconuts that need to be hit back. They make a strange squeaking noise before they shoot. This variety often appears in pre-boss levels and serve as mini-bosses. Gray Electrogoombas only shoot fire, and therefore Mario must use shells to destroy them.

As the forms become more powerful they look more like octopi.
