Darn, A.K.A. Experiment 576, is an illegal genetic experiment created by Jumba Jookiba. He is designed to destroy dams.
Experiment 576 was the 576th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to destroy dams.
576 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 Darn.
Darn is a gray hammerhead shark-like experiment.
