Jam

Jam, A.K.A. Experiment 202, is an illegal genetic experiment created by Jumba Jookiba. He is designed to use his high-pitched shriek to jam radar.

BioEdit
Experiment 202 was the 202nd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to jam radar with his high-pitched shriek.

202 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.

Stitch! The MovieEdit
All of the experiment pods were released and scattered across the island of Kauai, with 202's pod landing on a cliff face's ledge by a waterfall.

202's pod was later accidentally moved by a frog off the ledge and into the waterfall, activating the experiment, which then flew off to cause trouble.

Lilo & Stitch: The SeriesEdit
Presumably, 202 was captured by Lilo and Stitch at an unknown point and named Jam.

Leroy & StitchEdit
The first 624 experiments, including Jam, 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 Jam 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.
