Greensleeves, A.K.A. Experiment 342, is an illegal genetic experiment created by Jumba Jookiba. She is designed to revert objects to their Middle Ages equivalents.
Experiment 342 was the 342nd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to revert objects to their Middle Ages equivalents.
342 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.
Jumba was inspired to create her after looking through an earth book about King Arthur. Hence her powers change things back to the way they were in story middle ages which can be different then actual historical middle ages. This also explains why she doesn't quite fit in with the other 300 series (Psychological), as Jumba created her on a whim. By turning things back to the way they were in the Middle Ages, she makes places easier to conquer or destroy.
At the unknown point, he was activated, captured, tamed and named Greensleeves.
Jumba unintentionally programmed Greensleeves to be a lady. So she is rather polite and gentle, though she does have a small mischievous streak in her. She uses her power not out of an evil intent, but out of a genuine belief that people will be happier that way. It was because of the 'flaws' and because she tried to change some of his scientific equipment that Jumba dehydrated her soon after she was created.
Greensleeves is a a green bear-like experiment with short fuzzy ears perched on her head, along with two antennae, white patches on her belly, around her eyes, and on the inside of her head, a light green shield-shaped marking on her forehead and a darker green sword-like marking on her chest.
To turn things back to the way they were in the Middle Ages. She has an extra set of retractable arms.
She isn't very strong. Instead she was designed to do her work under the protection of several other experiments. She also can't climb.
- Greensleeves is described by the experiment computer screen that says "Experiment 342 Primary function: Reverter of objects to their Middle Ages equivalence".
