Boxboom, A.K.A. Experiment 273, is an illegal genetic experiment created by Jumba Jookiba. He is designed to be a pro-boxer and box you all over the place, making you sore breaking your bones. His one true place is as a boxing champion.
Experiment 273 was the 273rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be a pro-boxer and box you all over the place, making you sore and breaking your bones.
273 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.
Boxboom is a orange, brown, and yellow kangaroo-like experiment with three red boxing gloves (two are on his hands, and one is at the end of his tail).
