Experiment 355 swaps minds of Gantu and Hämsterviel just about he was to transport it. Lilo meets a girl named Victoria who also joins her hula class. However, Mertle will stop at nothing to try and befriend her so that she will not be Lilo's friend. Lilo then attempts to prove that she's normal by throwing a "Lilo's Not Weird" party. However, 355 appears, resulting in Lilo, Stitch, Jumba and Pleakley swapping bodies. Lilo must make sure the party is successful while Stitch has to pretend to be her. (thetvdb.com)
