Experiment 140 was the 140th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to change the location of your house. What Jumba wanted from 140 was an evil experiment that would tear apart complicated wiring and computer systems. What he got was a small cute pink pig-like experiment with no desire to destroy anything. However at night 140 transforms into a purple, four-legged added demon that proceeded to carry out his primary function. In the morning he goes back to a little pink pig experiment.
140 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 Changeling.
Changeling is a small pink piglike experiment.
