Waistrel, A.K.A. Experiment 440, is an illegal genetic experiment created by Jumba Jookiba. He is designed to steal food and make them go to waste.
Experiment 440 was the 440th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to steal food and make them go to waste.
440 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 Waistrel.
Waistrel is a yellow-green Stitch (626)-like experiment.
