Chameleo Arm is a very large chameleon-like creature who can change color at will, even after Paint Kirby forcibly paints him after eating a ball of paint spat out by Chameleo Arm. He has two hook-like hind legs similar in shape to a fishing hook. Chameleo Arm has horn-like protrusions on the back of his head. Down his spine, Chameleo Arm has many rounded scales and striped markings. Chameleo Arm has large sparkling blue eyes that take up a majority of his entire face.
