The Shape Japer, or just Shape Japer, is one of the Meanies, and is a purple ball with a permanent angry face, a grin, and sharp teeth. She's usually the cause of things changing shape or size, such as mops, and builders poles or other shapes having problems. She is the easiest meanie to defeat and is the nicest meanie. She flies though the air and doesn’t know how to speak well, but laughs maniacally. She is able to change her shape from sphere to cube at will.
