Ben, A.K.A. Experiment 312, is an illegal genetic experiment created by Jumba Jookiba. He is designed to get inside the filters of a space ship hyper-drive and clog them, causing severe complication for the pilots. He is the upgraded version of Millie (220) and Missy (219).
Experiment 312 was the 312nd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to get inside the filters of a space ship hyper-drive and clog them, causing severe complication for the pilots.
312 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 the unknown point, he was activated, captured, tamed and named Ben.
Ben is a giant green caterpillar-like experiment with twelve limbs, koala-like face with a wide mouth, large blue nose, black eyes and Nosy-like ears. He looks like a male version of Millie (220) but with a different shade of green skin.
