Poki, A.K.A. Experiment 036, is an illegal genetic experiment created by Jumba Jookiba. He is designed to poke holes in water containers. His one true place is next to a carton of milk which is in front of cats. He is voiced by Frank Welker.
Experiment 036 was the 36th experiment created created by Jumba with Hämsterviel's funding. He was designed to use his spiky tail to poke holes in water containers. 036 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 an unknown point, 036 was presumably activated, captured by Lilo and Stitch and named Poki.
In the film's opening, Poki can be seen with Slushy as the latter sells Shave Ice.
Later, the first 624 experiments, including Poki, 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.
Poki 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.
