This actually wasn't a pilot.

I did a lot of research, and apparently the show never had a pitch pilot, it was pitched using a show bible (which is publicly available) and just skipped straight to episode 1. What we have found so far is nothing more than early sketches and animations from the show. This article linked below explains the full history of the show's development and says nothing about a pilot. https://www.awn.com/animationworld/man-two-heads-shows
