Squeak

Squeak, A.K.A. Experiment 110, is an illegal genetic experiment created by Jumba Jookiba. He is designed to annoy people with his non-stop talking. Squeak is voiced by Rob Paulsen.

Bio
Experiment 110 was the 110th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to irritate people by talking non-stop.

110 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, Experiment 110 was activated and captured by Jumba.

Lilo & Stitch: The Series
In "Spike," Jumba tested a reprogramming device on 110, without success.

Leroy & Stitch
The first 624 experiments, including Squeak, were round 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 Squeak 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 failsafe.

Trivia
one true place is as Melty's assistant at the recycling plant.
 * Squeak resembles Little Blabbermouse from Merrie Melodies.
