Octopalmer, A.K.A. Experiment 470, is an illegal genetic experiment created by Jumba Jookiba. He is designed to drain life energy. His one true place is as the "OAP: Adventurers" club mascot. (OAP - Old Age Pensioner)
Experiment 470 was the 470th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to drain life energy (does so by using his 8 long tentacle like fingers on each hand that he uses to secure his targets then uses his life draining tendrils from the palm of his hand to drain his victims energy).
470 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 Octopalmer.
Octopalmer is a black octopus-like experiment.
It is possible to reverse the effects of experiment 470 by patting him on the head while he has you secured this infuses the target with artificial energy for 24 hours.
