Crusty, A.K.A. Experiment 414, is an illegal genetic experiment created by Jumba Jookiba. He is designed to spread mold on bread.
Experiment 414 was the 414th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to spread mold on bread. 414 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.
Possibly at an unknown point, 414 was activated, captured, and named Crusty.
The first 624 experiments, including Crusty, were rounded 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 Crusty 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Crusty is a blue meerkat/koala/Stitch-like experiment with knife-like paws.
- Crusty's pod color is red.
