Cal, A.K.A. Experiment 187, is an illegal genetic experiment created by Jumba Jookiba. He is designed to perform work such as carrying objects on his back.
Experiment 187 was the 187th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to perform work such as carrying objects on his back.
187 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 Cal.
