Gigi, A.K.A. Experiment 007 and Yapper, is an illegal genetic experiment created by Jumba Jookiba. She is designed to sit, lie down, fetch, and annoy Jumba's neighbors with her constant yapping. Her one true place is with Mertle as her pet.


Experiment 007 was the 7th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to do tricks, lick her owner's face, fetch the morning paper, and annoy Jumba's neighbors with her constant yapping. 007 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.

Lilo & Stitch: The Series


Gigi barking at Stitch

At an unknown point, Experiment 007 was activated and adopted by Mertle, who named her Gigi.

In "Yapper", Mertle showed Gigi off to Lilo and Stitch, and revealed that she was entering her in the junior dog show in Honolulu. However, when Gigi's yapping began to annoy Stitch, the latter swallowed her whole. Mertle screamed in horror until Lilo dragged Gigi out of Stitch's stomach and gave her back to Mertle.

Enraged, Mertle called both Lilo and Stitch "riffraff", and took Gigi to a pet salon to get her cleaned up. Hoping to win Mertle's friendship by beating her Gigi, Lilo traveled to Honolulu with Jumba and Pleakley, and entered Stitch in the same dog show, claiming he was a rare blue-furred ectoplasmic detection dog to impress the judges.

Lilo and Mertle entered their "dogs" into all the competitions, which took place the next day while Jumba and Pleakley went sightseeing. However, both Stitch's temper (when he fought with a contestant's dog after the latter sniffed him) and overconfidence caused him to lose the first two rounds. In the final competition, Mertle secretly gave Stitch extra strong coffee to make the latter go crazy so that Gigi would win.

Mertle's plan was successful at first until Gantu suddenly burst into the premises searching for her "dog". Stitch impulsively attacked Gantu, who fired his plasma gun uncontrollably, but a stray plasma blast caused the ceiling to collapse on top of Stitch. Gantu then took Gigi from a terrified Mertle, after which she complained to Lilo.


Gigi with Mertle

Because Gigi was Stitch's cousin, Lilo promised to save her from Gantu. She then gave Stitch more coffee intentionally, enabling the latter to defeat Gantu and get Gigi back safe and sound.

Grateful but indignant, Mertle gave the "Best in Show" trophy to Lilo. However, when Lilo saw how much Mertle truly cared for Gigi, the former decided to leave Gigi with Mertle.

Gigi reappeared in "Amnesio", being walked by Mertle and the hula girls.

In "PJ", Gigi and a couple of regular dogs attacked Lilo's substitute teacher wearing squeaky shoes shaped like dog biscuits, which was one of PJ's many pranks.

Leroy & Stitch

Gigi was seen being walked by Mertle, the latter stopping to taunt Lilo before moving on.

Later, the first 624 experiments, including Gigi along with Mertle, 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.

During the following battle between the experiments and the Leroy clones, Mertle with Gigi tried to avoid attacking Leroys. When Mertle and Gigi were saved from a Leroy by Clip, Gigi revealed her ability to speak and her status as an experiment, then pushed Mertle out of the way of a Leroy's plasma blast.

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.

Following the battle, Gigi declared that she wanted to be part of Lilo's ʻohana, prompting Mertle to join it with Gigi.



Gigi is a white Shih Tzu-like experiment with a purple bow, black eyes and a little nose.

Special Abilities

Gigi has an annoying bark and the typical abilities of a dog, such as sitting, fetching and licking her owner's face. She can also speak fluent English very well.
