Nosox

Nosox, A.K.A. Experiment 204, is an illegal genetic experiment created by Jumba Jookiba. He is designed to make socks disappear. He was captured by Gantu, but was rescued in "Snafu". His one true place is at Kokaua Laundry Store. He is voiced by Frank Welker.

Lilo & Stitch: The Series
Experiment 204 was the 204th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to eat socks and thus make them disappear. 204 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.

204's pod was one of the 12 experiment pods recovered by Lilo and Stitch in "Drowsy".

At an unknown point after this, Experiment 204, named Nosox, was presumably activated and captured by Gantu, as he was mentioned in "Amnesio" when Hämsterviel said, "After you sent me a sock hider..."

Nosox appeared in "Snafu", and was freed along with Gantu's other captive experiments by Lilo, Stitch, and several other experiments in a rescue mission.

Leroy & Stitch
The first 624 experiments, including Nosox, 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.

It is unknown whether or not Nosox 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 fail-safe.

Stitch! anime
Nosox made an appearance in a later episode of the Stitch! anime along with Shrink, Squeak, Clip, and Retro.
