Octoguy

Octoguys are enemies appearing in the game Super Mario Galaxy and Super Mario Galaxy 2. They resemble fat, dark pink Octoombas with lighter pink spots. They are different from other Octoombas because they can spit many rocks at a time and will attempt to run away at times.

Super Mario Galaxy
In Super Mario Galaxy, these enemies were quite rare, only appearing in mass numbers in the Honeyhive Galaxy, the Gold Leaf Galaxy, and the Deep Dark Galaxy. In the Honeyhive Galaxy, they appeared in the water-filled planet, trying to prevent Bee Mario from getting to the Queen Bee. They also appeared on the Queen Bee's planet. In the Gold Leaf Galaxy, they appeared in the final planet of the second mission in the water-filled section. In the Deep Dark Galaxy, they guarded a Fire Flower that was needed for Mario or Luigi to proceed through the level.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Octoguys were much more common. They first appeared in the Boulder Bowl Galaxy and later appeared in the Honeyhop Galaxy, and Shiverburn Galaxy's Prankster Comet mission.
