Hotcold, A.K.A. Experiment 189, is an illegal genetic experiment created by Jumba Jookiba. He is designed to switch the hot and cold valves on sink faucets. His one true place is at the hotel, reminding people which faucet is hot, and which one is cold.
Experiment 189 was the 189th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to switch the hot and cold valves on sink faucets.
189 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 Hotcold.
Hotcold is a small green monkey/pig-like experiment with short ears, a little nose, beady eyes, a small mouth, body, arms and legs and a round tail.
