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. Poki is voiced by Frank Welker.
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.
