Tub, A.K.A. Experiment 162, is an illegal genetic experiment created by Jumba Jookiba. He is designed to be a hot tub but hates water.
Experiment 162 was the 162nd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be a hot tub.
162 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 Tub.
