Gigi

Gigi, A.K.A. "Yapper" and Experiment 007, is an illegal genetic experiment created by Jumba Jookiba. She is Mertle's pet dog and appears in the Lilo & Stitch TV series episode "Yapper." She also appears in the film Leroy & Stitch and could talk, much to Mertle's astonishment. Gigi's voice consists of two actors, Frank Welker (vocal noises) and Tress MacNeille (speaking voice).

Personality
Gigi is a white Shih Tzu-like experiment with a purple bow. Designed to annoy people with her constant barking. She behaves like a typical "good dog": does tricks, licks her owner's face, fetches the morning paper, etc. Because of her appearance and behavior, 007 was adopted by Mertle and wasn't recognized as an experiment until Jumba saw her. Her episode is named "Yapper" after the nickname Lilo gave her, but she is officially "Gigi" on the experiment name list in Leroy & Stitch. Her one true place is with Mertle, as her pet. In Leroy and Stitch, it is revealed that she can speak English very well. At the end of the movie, Mertle joins Lilo and Stitch's Template:Okinaohana because Gigi wants to be in it with the rest of Jumba's experiments.

Trivia

 * Gigi did not speak in the Lilo & Stitch TV series. However, in the movie Leroy & Stitch, it was revealed that she could actually talk and says, "Nice one, cousin." Shen then says, "Look out!" and pushes Mertle out of the way of an incoming laser blast.
