Neg, A.K.A. Experiment 381, is an illegal genetic experiment created by Jumba Jookiba. He is designed to make you all naggy so everyone is annoyed with you.
Experiment 381 was the 381st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to make you all naggy so everyone is annoyed with you.
381 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.
At the unknown point, he was activated, captured, tamed and named Neg.
