After Lilo and Nani and Agent Bubbles rescue Stitch from Jumba, and officially make him a part of their ohana, they learn that since he is Experiment 626, then there six-hundred and twenty-five more just like him. The Galactic Council wants to have the other experiments (which are dehydrated into marbles for easy transport) destroyed because they are dangerous and it'll be a lot of work to rehabilitate them all. Lilo is able to convince the Grand Councilwoman otherwise, and she and Stitch, and Pleakley, journey into space to go find them. But they must get home in time for the special televised hula event that the duo are participating in. Unfortunately, a rough law enforcer is also after the experiments (since he's a double agent). Lilo and Stitch have to break Jumba out of jail because he knows more about the experiments than anyone else. At the lab, Stitch sets a female experiment (624) free from a cell and falls in love with her. Meanwhile, David is thinking about asking Nani "the big question."
