Memory:Gelatinous cube

The first thing you'll note when a gelatinous cube is nearby is the total lack of any plant life or organic debris in the area. Gelatinous cubes are almost translucent with, sometimes, a slight green coloring. If you are lucky the cube will have some pieces of its last meal inside, so you'll be able to see it. So take a close look at those floating skulls! A translucent structure of almost solid jelly slurping across the ground. As it moves, it engulfs items and dissolves them. It is larger than you, so you feel as though it were a good idea not to look like a slice of pizza.
