He, A.K.A. Experiment 561, is an illegal genetic experiment created by Jumba Jookiba. He is designed to radiate heat (does so by using his spines and markings along his back that glow and produce excessive amounts of heat; this heat will steadily increase the temperature of his surroundings, which can cause long term problems for any planet that he is activated on). His one true place is helping to generate steam for a sauna.
Experiment 561 was the 561st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to radiate heat.
561 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 He.
- He's pod color is blue.
- He is described by the experiment computer screen that says "Experiment 561 Primary function: Tattle".
