Swirly

Swirly, A.K.A. Experiment 383, is an illegal genetic experiment created by Jumba Jookiba. He is designed to hypnotize his victims into obeying the next order or suggestion they hear. His one true place is hypnotizing people at children's parties.

Bio
Experiment 383 was the 383rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to hypnotize his victims to obey the next order or suggestion they heard.

383 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.

All of the experiment pods were released and scattered across the island of Kauai, with 383's pod landing on a beach shore.

Lilo & Stitch: The Series
When the tide came in, 383's pod got wet, activating him. 383 then hypnotized a surfer, who had witnessed his activation, and left the scene.

After hypnotizing a tourist, 383 was caught in a fight between Lilo, Stitch and Gantu, which ended with Lilo and Stitch capturing 383.

Lilo and Stitch then took 383 back to their house, where Lilo named 383 Swirly. However, Swirly was able to escape and hypnotized both Lilo and Stitch.

Gantu later captured Swirly and was temporarily hypnotized by the latter while back at his ship. Experiment 625 was fascinated and had some fun with Gantu. Even Hämsterviel was intrigued and toyed with Gantu a bit before snapped him out of his trance. Hämsterviel then told Gantu his clever scheme that involved using Swirly on the "Look at This!" show.

Gantu used Swirly to hypnotize the manager into putting him on the "Look at This!" show. He then planned to use Swirly to hypnotize the show's viewers into slaves. Lilo and Stitch, who both happened to be on the show, were still under Swirly's hypnosis from before.

Jumba, who was watching the show back home, soon found out what was going on. He then came to the show in person and snapped Lilo and Stitch out of their trances.

Lilo and Stitch then stopped Gantu from hypnotizing the show's viewers, recaptured Swirly, and found him a one true place at parties.

In "The Asteroid," Swirly was one of the six experiments who Stitch convinced to come with him and Lilo to save Earth from an approaching asteroid. Swirly hypnotized the asteroid's local asteroid squatter to prevent him from distracting them.

Leroy & Stitch
The first 624 experiments, including Swirly, were round up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.

It is unknown whether or not Swirly participated in the following battle between the experiments and the Leroy clones.

The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song Aloha `Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
