Puyo

Puyo are putty-like in appearance, and are able to shape shift. They move by altering their shape. Their colors range from yellow, red, to green. In a corridor before you find the Plasma beam there is a group of white puyo, which tend to spark debates if they are indeed puyo. This is because they are white and arranged in a pyramid shape. In Metroid Fusion there is an X clone which are red and have spikes.
