Zirconia, A.K.A. Experiment 597, is an illegal genetic experiment created by Jumba Jookiba. She is designed to compress mineral matter into high-quality gemstones.
Experiment 597 was the 597th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to compress mineral matter into high-quality gemstones
597 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 some point she was activated, tamed, and named Zirconia.
The first 624 experiments, including Zirconia, were round up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
It is unknown whether or not Zirconia participated in the following battle between the experiments and the Leroy clones.
The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song Aloha Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
