Puyo are putty-like in appearance and are able to shapeshift with their elastic bodies. They move by stretching their shape and seemingly 'hop' from one location to the other; if Samus is near them, they will jump high into the air in an attempt to land on her, causing damage if they do. Their color is commonly yellow, but green and red variants also exist. In a corridor before Samus finds the Plasma Beam in Maridia however, there is a group of white Puyos, huddled together in a small group. These rare white Puyos do not seem to be at all aggressive as other types.
In Metroid Fusion, there are infected Puyos and/or X Parasites mimicking the former; these unnatural variants are slightly larger, are only seen with a red color and have spikes on their surfaces. Like the authentic variants, they can jump to considerable heights.

- The slime creatures that get infected by X Parasites containing Human DNA and turn into Zombie researchers may actually be a normal variation of Puyos.
