Octopuses are enemies appearing in the game Super Mario Galaxy and Super Mario Galaxy 2. They are quite different from real-world octupuses, as they do not swim. Rather, they are giant, gray Octoombas with pale spots and a blue antenna. They are larger in size than their Octoomba sub-species 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. To defeat them, Mario has to send back the coconuts they shoot by spinning. One pair that shoot only fireballs that are found in the Space Junk Galaxy must be destroyed by the player throwing shells towards them. They mostly have to be defeated in order to make a bridge appear.

Super Mario Galaxy 2
In Super Mario Galaxy 2, they reappear 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: their only appearance where defeating them is not mandatory to progress forwards. They still shoot coconuts and fireballs.
