Rocto

Gray Octoombas are enemies appearing in the game Super Mario Galaxy and Super Mario Galaxy 2. They are giant, gray Octoombas with pale spots and a blue antenna. They are very large in size and have two round body segments with four small feet at their bottom.

Super Mario Galaxy
In Super Mario Galaxy, these enemies only appeared in areas with airships in them and they would usually hide in barrels or stand on platforms until Mario appeared within their range, after which they would shoot Mario with melons or fireballs as their main form of attack.

Super Mario Galaxy 2
In Super Mario Galaxy 2, they reappear again but only in the Shiverburn Galaxy where they act as the final enemy defense line before facing Prince Pikante.
