Rhomp

Rhomps are Spindel-like enemies that appear in Super Mario Galaxy 2. Only 18 Rhomps are found in the entire game, all being found in the sand slide area of the Slipsand Galaxy. Here, they attempt to flatten Mario or Luigi, which makes him lose a life instantly. They resemble tube-shaped stones with smiley faces and a circular stone with square designs on it attached to each side. While similar to Spindels in both design and behavior, Rhomps have several differentiating features, such as smooth stone skin and no teeth or eyebrows. A Rhomp's face is very similar to that of a Grumblump.
