Experiment 455 or "Mary" is a round, pudgy, peach-colored experiment designed to grab enemies with her antennae-like ears and literally bounce them to kingdom come. She was first discovered by Lilo and Stitch after the events of "Shortstuff'. 455 then proceded to bounce the locals around like kids on pogo sticks until her eventual capture by Gantu, who, after noticing that she looked a lot like his high-school rival, Maria Evestba, named her out of spite. She is saved by Stitch in the near-end and was then seen to enjoy exercise. Mary soon points out that she only bounces them because she thought they needed to get in shape. So, with a little help from Kixx (601), Mary now works with him in his new gym.
