Squidly, A.K.A. Experiment 591, is an illegal genetic experiment created by Jumba Jookiba. He is designed to eat up fish and cause a fish famine.
Experiment 591 was the 591st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to eat up fish and cause a fish famine.
591 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 Squidly.
