Pooperson, A.K.A. Experiment 444, is an illegal genetic experiment created by Jumba Jookiba. He is designed to pollute enemy water supply (does so by spitting a compound he secretes through his saliva called "Fe-C-Lite").
Experiment 444 was the 444th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to pollute enemy water supply.
444 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 Pooperson.
Fe-C-Lite causes extreme discomfort when consumed and can also make those affected by it to become dehydrated. Fe-C-Lite is the universes most powerful fertilizer and is illegal in 662 star systems.
