Burr, A.K.A. Experiment 141, is an illegal genetic experiment created by Jumba Jookiba. He is designed to make it really cold.
Experiment 141 was the 141st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to make it really cold.
141 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 Burr.
Burr is a blue lizard with a fish-tail.
