Octoomba

An Electrogoomba is an enemy in Super Mario Galaxy. It is an alien, amphibious Goomba. 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.

Appearance
Electrogoombas are odd-looking Goombas. They have smooth skin with a blue head and yellow spots all over their bodies. They have a round mouth, like a Snifit, and attack with a headbutt. Unlike regular Goombas, Electrogoombas only patrol a very small set area. They also have yellow glowing eyes and a small antenna on the top of their head. Also, they don't have a small body, unlike the normal Goomba.

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.

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