Drowsy, A.K.A. Experiment 360, is an illegal genetic experiment created by Jumba Jookiba. He is designed to put individuals to sleep by simply bleating, although the effect is near-permanent; only water in the victim's face will awaken them, and other experiments are not affected as much. His one true place is putting insomniacs to sleep. He is voiced by Tress MacNeille.
He was activated when Stitch squirted his pod with a water bottle sprayer, then used him to put a restless Lilo to sleep. When Gantu and Reuben later attempted to use 360 to kidnap Regis Philbin, Lilo and Stitch managed to protect him. In another episode, Lilo put Stitch to sleep with 360 in order to release PJ (133), but Stitch oddly managed to wake up on his own.
Drowsy is a grey sheep-like experiment with striped ears, short arms and legs, black fingers and toes, and that can walk on its hind legs.
Drowsy's bleat causes anyone who hears it to enter a near-permanent sleep.
Water sprayed in the victim's face is the one surefire way to awaken them. Also, if the victim blocks their ears, Drowsy's sleep-inducing bleat will have no effect. Additionally, other experiments under Drowsy's effects are not affected as much, and will likely wake up on their own.
- Drowsy's sleep-inducing bleat and sheep-like appearance are likely derived from the mental exercise of counting sheep in an attempt to fall asleep.
- A recurring irony has occurred with Drowsy. Stitch originally used him to get Lilo to fall asleep, and in his second appearance, Lilo used him to put Stitch to sleep.
- Stitch somehow managed to wake up on his own while under Drowsy's effects, possibly indicating that other experiments are not affected as much.
- Drowsy's pod color is yellow.
- Drowsy is described by the experiment computer screen as, "Experiment 360. Primary function: Sleep inducer".
- Oddly, when Drowsy's image is reflected off of Stitch's eyes in The Origin of Stitch, he is not yawning for some reason. It is possible that Drowsy's yawning image was taken from Leroy & Stitch.
- Drowsy appeared on the DVD cover of Leroy & Stitch, along with Lilo, Stitch, Jumba, Pleakley, Doubledip, Fibber, Amnesio, Woody, Shredder, Ploot and Felix, with Leroy flying above in a one-man space shuttle.
