Experiment 562 was the 562nd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to have a hard shell that you couldn't break it.
562 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, she was activated, captured, tamed and named Hardy.
Hardy is a green sea turtle-like experiment.
