Fetchit, A.K.A. Experiment 090, is an illegal genetic experiment created by Jumba Jookiba. He is designed to fetch the morning newspaper for Jumba. His one true place is with Mrs. Hasagawa as one of her "cats".
Experiment 090 was the 90th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to fetch the morning newspaper for Jumba.
090 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. Against statistically unlikely (but not impossible) odds, several experiment pods landed in one location: Mrs. Hasagawa's yard, 090's pod being one of them.
At an unknown point, Mrs. Hasagawa mistook 090's pod for an apricot and washed it, activating the experiment. However, as 090 was not a very evil or destructive experiment, he was able to live a peaceful life with her, due to the latter seeing the former as a mere stray cat who needed a home.
When Lilo and Stitch discovered that Mrs. Hasagawa kept several experiments as pets, they thought they were a danger to her and, along with Jumba and Pleakley, decided to capture them all. 090 was then captured by unknown means.
090 and the other experiments were about to be taken away, but were returned to Mrs. Hasagawa when Lilo and Stitch saw how much she cared for them. 090 was then named Fetchit.
The first 624 experiments, including Fetchit, 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 Fetchit 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 fail-safe.
Fetchit is a green dog-like experiment with black eyes and nose and pink ear insides.
