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".

Bio
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.

Lilo & Stitch: The Series
204's pod was one of the twelve experiment pods recovered by Lilo and Stitch in "Drowsy".

At an unknown point after this, Experiment 204 was presumably activated and captured by Gantu.

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.
