Holio, commonly referred to as Experiment 606, is an illegal genetic experiment developed by Jumba Jookiba. He appears in the Lilo & Stitch series. He is designed to transform into a matter-sucking, galaxy-destroying black hole. Sucking up trash and building waste is his one true passion.
Holio is a very obedient person and is willing to assist in the cleanup of debris as his one true location when he is not using his abilities. In supporting Stitch's rebellion to drive out Gantu, he demonstrates his loyalty to and assistance from his companions. Holio is a little, red experiment that resembles a chipmunk and has a wide mouth with two protruding teeth.
