Experiment 287 was the 287th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to undo the work of 141.
287 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, 287 was activated, captured, tamed, and named Burl.
Burl is a small, ferret-like experiment. She is a dark pink color with a light purple chest, blue nose, large eyes, and small ears. Her tail resembles a whale's tail. She has four fingers on each hand and three claws on each foot.
