Cloudy, A.K.A. Experiment 320, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to depress others with constant rain. His one true place is raining on Mrs. Hasagawa's produce at her fruit stand, suggesting he may be one of her "cats".
Experiment 320 was the 320th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to depress others with constant rain.
320 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 some point, 320 was presumably activated, captured, and named Cloudy.
Later, the first 624 experiments, including Cloudy, 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 Cloudy 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Cloudy is a grey cloud-like experiment with small black eyes, a thin mouth and dark grey markings on his body.
Cloudy can produce a constant heavy rainfall, depressing his victims.
