383 - Swirly
, A.K.A. Experiment 383, is an illegal genetic experiment created by Dr. Jumba Jookiba. He is designed to hypnotize people into obeying the next order or suggestion they hear. If no order or suggestion is issued within a few minutes of the initial hypnosis, the effect is nullified. To break the hypnosis, one need only snap their fingers. His one true place is hypnotizing people at children's parties.


Swirly is a small turquoise koala-like experiment with a huge head, an expressionless face with a little mouth, little nose, huge black pupil-less eyes (with white swirling lines when using his powers), rabbit-like ears, a single small antenna on the middle of his head, and a small doglike tail.


Swirly is a troublesome experiment, although very mute at that. He is quite active with his hypnosis, as it is performed at the most inadequate of times to humiliate others, but he himself is otherwise harmless. He often stares into space when not using his powers, being somewhat blank-minded.


Lilo & Stitch: The SeriesEdit

Experiment 383 was the 383rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to hypnotize his victims into obeying 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.

When the tide came in, 383's pod got wet, activating the experiment. 383 then hypnotized a surfer, who had witnessed his activation, and left the scene.

After hypnotizing a tourist, 383 was ambushed and captured in a container by Gantu. A fight then ensued between Lilo, Stitch and Gantu, which ended with Lilo and Stitch retrieving 383.

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

Gantu later recaptured Swirly and was briefly hypnotized by the latter back at his ship. Experiment 625 was fascinated by this and amused himself by making Gantu do silly stuff. Hämsterviel also became intrigued after seeing this, and toyed with Gantu a bit before snapping him out of his trance. Hämsterviel then told Gantu his clever scheme that involved using Swirly on the Look at This! show.

Later, Gantu arrived at the studio, where he used Swirly to hypnotize the manager into putting him on the Look at This! show. He then planned to hypnotically turn 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 on TV back home, soon found out what was going on. He then came to the show in person and managed to snap Lilo and Stitch out of their trances so they could rescue Swirly.

Gantu attempted to use Swirly to hypnotize the show's viewers into slaves, but this failed when Lilo and Stitch recaptured Swirly, leaving Gantu holding the bag, and later found him a one true place at children's parties.

In "The Asteroid", Swirly was one of the six experiments that Stitch convinced to come with him and Lilo to save Earth from an approaching asteroid. During the journey, Swirly hypnotized the asteroid's local asteroid squatter to prevent him from distracting the others, who managed to use the ship's hyperdrive engine to safely redirect the asteroid.

Leroy & StitchEdit

The first 624 experiments, including Swirly, were rounded 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.

Swirly participated in the following battle between the experiments and the Leroy clones by hypnotizing Leroys.

However, 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.

Stitch! animeEdit

Swirly made an appearance in the Stitch! anime where Hämsterviel used him to hypnotize Stitch into fighting for him. This episode also featured Plasmoid and Splodyhead who helped combat Stitch while he was hypnotized.
