Spineless, A.K.A. Experiment 295, is an illegal genetic experiment created by Jumba Jookiba. He is designed to make you lose your spine.
Experiment 295 was the 295th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to make you lose your spine.
295 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, 295 was activated, captured, tamed, and named Spineless.
Spineless resembles a shark, but he has two front legs, and his fin forms a third leg. Whether he has a fourth leg or not is unknown.
