Butter, a.k.a. Experiment 227, is an illegal alien experiment created by Jumba Jookiba. He is designed to be able to batter through thick doors and barricades. His one true place is with the police as a battering ram and in jumba's custody.
Butter is a large tan mammoth-like creature with a large head, two tiny little antennae, a big round green nose instead of trunk, green markings on his back, legs at the middle of his torso with external toes, a big hump near his face, and tusks as large as the entire front of his body.
Butter can batter through thick doors by using his tusks and large head.
