Stamen, A.K.A. Experiment 103, is an illegal genetic experiment created by Jumba Jookiba. He is designed to attract bees to himself to prevent pollination of flowers. He was captured by Gantu, but was rescued in "Snafu". His one true place is at a bee farm to attracts bees out of their hives to pollinate flowers.
Experiment 103 was the 103rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to prevent the pollination of flowers by attracting bees to himself. 103 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 after this, Experiment 103 was activated and captured by Gantu.
The first 624 experiments, including Stamen, 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.
It is unknown whether or not Stamen 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Stamen is a tan-grey, upside-down ice cream-shaped, mouse-like experiment with an oval body, little arms and legs, big ears, a big mouth, no tail, black eyes, a round blue nose and rabbit-like ears.
Stamen uses his floral attributes to attract colonies of bees to him away from fields of agriculture, thus causing pollination to be prevented.
