Hyuckster, A.K.A. Experiment 317, is an illegal genetic experiment created by Jumba Jookiba. He is designed to reply you with the word "Yuck!!!" He only says it if he hears somebody asking a question.
Experiment 317 was the 317th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to reply you with the word "Yuck!!!"
317 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 Hyuckster.
