Experiment 064 was the 64th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to makes you take a nap, (temporary).
064 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, 064 was activated, captured, tamed and named Nappifier.
Nappifier is a baby blue blanket-shaped experiment.
