Manners, A.K.A. Experiment 358, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to give people painfully perfect manners. With a wave of his hand, his victims become too polite to fight back. His one true place is with Mrs. Hasagawa as one of her "cats".
