Screwup, A.K.A. Experiment 085, is an illegal genetic experiment created by Jumba Jookiba. His intended purpose is unknown, as Jumba screwed up with him. All he does is lay down and do nothing. His one true place is relaxing.
Experiment 085 was the 85th genetic experiment created by Jumba with Hämsterviel's funding. His intended purpose is unknown, as Jumba screwed up making him. All he does is lay down and do nothing.
085 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, and named Screwup.
The first 624 experiments, including Screwup, 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 Screwup participated in the following battle between the experiments and the Leroy clones, but it is very doubtful.
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.
Screwup is a pink puppy/flying squirrel-like experiment with a bare head, aside from very few hairs sticking out here and there. Two stubby antennae stand on his head. He has a big red nose with two beady eyes beside it. He has three spines, and his underbelly is white with a tint of pink. His hands and feet are gecko-like, and his arms and legs are about the same size. When he sits up he looks roughly similar to a naked mole rat.
