He was portrayed by Michael Dahlen.
Flesh Balls resembles a man with messed up hair, except he has sagging cheeks and genitalia on his chin. He wore a black scarf to hide his genitalia and a yellow jacket.
Flesh Balls was one of the aliens working for Serleena, along with Scrad and Charlie, Pineal Eye, Mosh Tendrils, Corn Face and Dog Poop, looking for Agent K as they believed he knew the location of the Light of Zartha. Normal attacks were useless against him, until Agent J reminded Agent K that he's a Ballchinian, and then Kay kicked his chin.
