Lilo, Stitch, Jumba and Pleakley have finally caught all of Jumba's genetic experiments and found the one true place where each of them belongs. Stitch, Jumba and Pleakley are offered positions in the Galactic Alliance, turning them down so they can stay on Earth with Lilo. But Lilo realizes her alien friends have places where they belong, and it's finally time to say "aloha." Meanwhile, Gantu has left Earth and broken Doctor Jacques Von Hamsterviel out of prison, who's planning to create and clone a new experiment named "Leroy," one that will allow him take over the galaxy. (Old version title - Lilo and Stitch 3 Hamsterviel's Revenge)

Included on the DVD release of the film is the animated short The Origin of Stitch. The short has a total running time of 4:35 minutes and serves as a bridge between Stitch Has a Glitch and Stitch! The Movie. In the short, Stitch discovers Jumba's secret computer that reveals what creatures Jumba had used to create Stitch, and also hints at his other 625 experiments. Stitch is scared to find out what a monster he is, only for Jumba to come and explain how he found love when he met Lilo. The short was directed by Mike Disa and co-directed by Tony Bancroft.
