Bonnie A.K.A. ​Experiment 149 ​is an illegal genetic experiment created by Dr. Jumba Jookiba. She is designed to work with Clyde to steal things without the victim's knowledge. Her one true place was originally in Kokaua Town Prison, but she was paroled in "Snafu".


Bonnie is a small, light green koala-like experiment with a yellow stomach, a slim body, small antennae, big dark blue eyes, girly eyelashes, a big head, a wide mouth with two fangs sticking out, a round nose, rabbit/mouse-like ears, two dark green marks on the back of her head, dark green, arrow-like patches on her arms and legs, and a yellow V-shaped stripe on her forehead.


Bonnie is the brains of the duo. She is an obsessive and compulsive stealer of things. However, this doesn't stop her from being quite a helpful friend to others. Her closest partner-in-crime is Experiment 150, Clyde.

Manipulative, cunning, streetsmart, and a great schemer, Bonnie has the qualities of a true, albeit amateurish criminal mind. She's normally quite laid-back in situations (unless maybe the cops or other enemies are after her). With such a carefree, social and almost friendly personality, it can be quite easy for the gullible to fall for her rotten tricks, namely Lilo and Stitch. Despite her deceptive nature and nasty ideals, Bonnie can still be a rude, tomboyish brat with little etiquette, as well as a bit short-tempered at times. She's got an extremely close bond with Clyde, despite the fact that they have argued a few times before. She's naturally just seeking thrill, fun and adventure, even if it means stealing a few things or joining in on brawls with her other experiment "cousins."

She and Clyde are also seen to be hoarders as well as thieves.


Lilo & Stitch: The SeriesEdit

Experiment 149 was the 149th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to work with Experiment 150 to steal many belongings and evade arrest. 149 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.

149 and 150's pods eventually made their way into a supply of doughnut holes at Kiki's Coffee Hut.

Officer Kaihiko, who was off duty, bought a bag containing two dozen doughnut holes at the coffee shack and (mistaking them for a new flavor) dipped 149 and 150's pods in his coffee, activating the two experiments, which proceeded to strip Kaihiko and hijack his police car.

The duo next made a vain attempt to break into Gantu's ship, but were forced to flee the scene when Gantu caught them in the act.

149 and 150 went on to cause countless robberies throughout the island, until they were tracked back to their hideout by Lilo and Stitch. There, 149 hatched a plan to encourage Lilo and Stitch's naughty behavior so that they would eventually show the two experiments how to break into Gantu's ship.

At first, Lilo and Stitch's unruly behavior posed as a distraction for 149 and 150 (named Bonnie and Clyde) while they stole from numerous places.

The following night, Bonnie and Clyde managed to convince Lilo and Stitch to help them successfully break into Gantu's ship. However, before the four could steal anything, they were ambushed and captured in containment orbs by Gantu. Lilo and Stitch were able to break out, though, and the four made a narrow escape.

When the criminal experiments discovered that the police had found and secured their hideout, Bonnie convinced Lilo and Stitch to allow her and Clyde to take cover in the Pelekais' house.

Bonnie and Clyde attempted to hide in Lilo's laundry, but were discovered by Pleakley while the latter was taking out the laundry, prompting Bonnie and Clyde to tie him and Jumba up and strip the house of everything. Jumba and Pleakley were later freed, and let Lilo and Stitch use The Red One to chase down Bonnie and Clyde.

While the two thieves were fleeing to their new hideout in Nani's dune buggy – along with all of the Pelekais' other possessions in tow – they were attacked by Gantu in his hovercraft, but saved by Lilo and Stitch, whom Bonnie and Clyde took back to their new hideout: the pre-robbed coffee shack.

The two crooks thought Lilo and Stitch were still on the level until they suddenly revealed their true colors: to re-infiltrate Bonnie and Clyde's hideout in order to capture them. When Stitch pointed a similar net cannon at Bonnie and Clyde, they attempted to escape out a window that was locked, but were blasted into a net by Stitch, handed over to Officer Kaihiko, and sent to Kokaua Town Prison.

In "Spike", Bonnie was one of the experiments in Pleakley's E.A.R.W.A.X. group, alongside Clyde. When Clyde used Fibber's lie-detecting ability to prove that Bonnie wasn't as intelligent as she claimed, nor was Clyde to blame for getting them both arrested, the duo got into a fight, which ended when Pleakley convinced Bonnie and Clyde to attempt hugging therapy on each other.

In "Snafu", Bonnie and Clyde were paroled so they could join Lilo and Stitch on a mission to rescue Gantu's captive experiments. They assisted by opening a passage in Gantu's ship so Stitch and the others could break inside.

Leroy & StitchEdit

The first 624 experiments, including Bonnie and Clyde, 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.

Bonnie and Clyde 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 fail-safe.

Stitch! animeEdit

Bonnie and Clyde made an appearance in the Stitch! anime where they escaped from Galactic Prison and traveled to the island in order to continue their primary function, which is stealing things. Because of this, they could be considered "incompletely rehabilitated." They have also revealed that they've tried to be good, but their programming interferes with it. It is unknown if they have truly turned good.


  • Bonnie is Experiment 149. However, in her debut, she is called 349, most likely due to Jumba's untidy database.
  • Bonnie normally has two fangs, but in "Spike", she has six fangs (four on the top and two on the bottom).
  • Bonnie is named after bank robber Bonnie Parker.
  • She speaks English like Reuben, but with a Mafia accent, pretty much to the one the real Bonnie had.
  • Bonnie's pod color is purple.
  • Bonnie is described by the experiment computer screen as, "Experiment 149. Primary function: Theft and evasion."
