Who is compared to Frankenstein's monster?
The film starts out with ex-Captain Gantu on his new spaceship (his original got destroyed in the first film), being hired by a hamster-like alien named Dr. Jacques von Hämsterviel to retrieve the other 625 experiments.
Meanwhile, on Earth, Stitch is still not fitting in and causes another disaster. Lilo Pelekai tries to encourage him by saying he's one-of-a-kind, comparing him to Frankenstein's monster. 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 Jumba's 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.
Meanwhile, Jumba is being held captive on the ship of Dr. Hämsterviel, who is surprisingly a small hamster/poodle/rabbit-like alien. Unable to intimidate Jumba, Hämsterviel activates Experiment 625, who has all of Stitch's powers, to attack him. While 625 has all of Stitch's powers, he is incredibly lazy, a terrible coward, and prioritizes in making sandwiches above all else.
