Experiment 063 was the 063rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to make people puff up like a balloon.
063 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, 063 was persumbably activated, tamed, and named Pufferizer.
Pufferizer is a dark yellow puffer fish-like experiment that stands on two legs.
