NPH, A.K.A. Experiment 184, is an illegal genetic experiment created by Jumba Jookiba. He is designed to give you a "Normal Pressure Hydrocephalus."
Experiment 184 was the 184th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to give you a "Normal Pressure Hydrocephalus."
184 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 NPH.
