Experiment 152 was the 152nd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to give you leftover food.
152 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.
Mama Frita is a little green experiment with two antennae on her head and a big puffy tail with thorns on her back.
