Dumbell, A.K.A. Experiment 163, is an illegal genetic experiment created by Jumba Jookiba. He is designed to annoy you by repeatedly ringing his bell.
Experiment 163 was the 163rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to annoy you by repeatedly ringing his bell.
163 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 Dumbell.
