Experiment 486 was the 486th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to grind meat.
486 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 Grindz.
Grindz is a brown experiment with a meat grinder for a head.
