Stitch! The Movie

Stitch The Movie is a directtovideo animated spinoff of Lilo amp Stitch, released on August 26, 2003. It is often considered more of a backdoor pilot for the spinoff series Lilo amp Stitch The Series rather than a sequel to the original film. The story is an introduction to Dr. Jumba Jookibas 625 experiments, which he created with the financing of Dr. Jacques von Hmsterviel.

Meanwhile on Earth, Stitch is still not fitting in and causes another disaster. Lilo tries to encourage him by saying hes oneofakind, comparing him to Frankenstein. Naturally, that just makes him feel worse. Suddenly, a crash is heard from below. Running downstairs, the pair encounters Gantu, breaking into their home. In the ensuing chaos, Stitch thrusts his belly out at Gantu, only to be blasted into a net. Gantu finds and takes a blue pod with the number 625 on it before abducting Jumba for interrogation. Lilo and Stitch manage to take Jumbas ship to chase Gantu into space and engage him in battle, before being defeated and falling back towards Earth.Back at the house, Lilo, Stitch and Pleakley find the container Jumba was hiding. Pleakley realizes that these are the other 625 experiments, in dehydrated form. He warns them not to tell anyone or put the experiments in water. Deliberately disobeying Pleakley, Stitch and Lilo retrieve the container and hydrate Experiment 221, who promptly escapes. ........
