Rocto

Octopuses 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 mostly 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 coconuts/watermelons or fireballs as their main form of attack. They are always found in pairs.

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. However, unlike its prequel, there are five instead of two. They also appear in the final galaxy, the Grandmaster Galaxy on the Platform Planet.
