Snooty

Snooty, A.K.A. Experiment 277, is an illegal genetic experiment created by Jumba Jookiba. He is designed to mine and enrich Snootonium, but as Earth mucus has the same chemical compound, Snooty will collect this as well. His one true place is as Victoria's pet, clearing her sinuses. Snooty is voiced by Frank Welker.

Lilo & Stitch: The Series
Experiment 277 was the 277th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to mine and enrich Snootonium, a rare element that has a similar chemical makeup as Earth mucus. 277 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.

277's pod eventually made its way onto a pickup truck's antenna. When the owner took the pickup through a car wash, the pod got wet in the wash, activating 277. After spooking the pickup's driver, 277 left in search of Snootonium-like mucus.

Drawn by her allergies, 277 frequently attacked Victoria, but each time he was warded off by Lilo and Stitch. They also prevented a persistent Gantu from taking the experiment, despite Victoria's protests.

At one point, 277 spooked Officer Kaihiko, who tried to convince the girls to get inside his police car where they would be safe. However, 277 still attacked relentlessly in an attempt to get to Victoria.

During one of 277's assaults on Victoria, Stitch challenged him. 277, upon detecting the Snootonium in Stitch's body, quickly attacked the latter and sucked him dry.

Lilo took Stitch home, where Jumba explained why Stitch was wiped out and that Snootonium was similar to Earth mucus, which also explained why 277 kept going after Victoria.

Meanwhile, Victoria was in a store looking for various items to slay 277 with. She then saw Gantu and decided to team up with him to slay the experiment. They tracked 277 down to his hive in the Hawaiian mountains, where Gantu used Victoria as bait to successfully draw 277 out.

Just then, Lilo arrived, shocked to see Victoria with Gantu. Victoria tried explaining that Gantu was helping her slay 277, but Lilo managed to convince her of Gantu's treachery. Gantu captured 277 by blasting him into a net, but the latter was then saved by Victoria and Lilo, who both fought Gantu for the experiment.

277, christened Snooty, seemed to like Victoria. When Snooty used his mucus-sucking power to clear Victoria's sinuses, the latter kept him as a pet.

Leroy & Stitch
In the film's opening, Snooty can be seen waving hello to Lilo, along with Babyfier and Amnesio.

Later, the first 624 experiments, including Snooty, 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.

Snooty participated in the following battle between the experiments and the Leroy clones by dodging Leroys' plasma projectiles.

However, 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.

Trivia

 * Snooty is an obvious parody of Count Dracula, except that Dracula sucks blood and can morph into a vampire bat at will.
 * Victoria originally mistook Snooty for a real vampire, and thus feared him.
 * Snooty is Victoria's first and only experiment she caught.
 * Snooty's pod color is normally red. In "Mrs. Hasagawa's Cats", he was seen in his pod form, and it was white.
 * Snooty is described by the experiment computer screen as, "Experiment 277 Primary function: Mine and enrich Snootonium."
