Shortstuff

Shortstuff, A.K.A. Experiment 297, is an illegal genetic experiment created by Jumba Jookiba. He is designed to sabotage mechanical devices. His one true place is as an amusement park ride.

BioEdit
Experiment 297 was the 297th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to enter machinery and sabotage in from within.

297 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to captureExperiment 626.

All of the experiment pods were released and scattered across the island of Kauai, with 297's pod landing in a sewage pipe.

Lilo & Stitch: The SeriesEdit
When lemonade from a broken lemonade stand trickled into the pipe, it touched 297's pod, activating him. Gantu grabbed 297, but the experiment was able to escape by pinching Gantu.

297 then proceeded to sabotage every ride in the nearby amusement park before being captured by Lilo and Stitch.

Lilo and Stitch took 297 back to the house, where Lilo named him Shortstuff. Shortstuff was able to escape containment, and attempted to sabotage Jumba's protoplasmic growth ray. However, in the process, the ray enlarged Shortstuff into a behemoth.

Shortstuff then went on a rampage, and faced off with the also enlarged Stitch. At first, Shortstuff was able to easily overpower Stitch, but when Stitch was shrunk back to his normal, functional size, the latter easily defeated Shortstuff.

Shortstuff was then found a one true place as an amusement park ride.

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