Update: It looks like there are multiple factions within Mediatonic debating over the actual anatomy of a Fall Guy. While senior concept Tudor Morris would have us believe that inside these beans reside horrific bird-human skeletons and useless nipples, principle concept artist Ash Kerins has presented an alternative theory. 

Kerins suggests that the beans are considerably smaller than humans, weight the same as an average pillow and are full of air, aside from their large, squishy heart. At this point, the only way to know for sure if by cutting one of them open. 

Original story: Some things should stay mysteries. The internet's desire to know more about Fall Guys has given rise to a horrific piece of official concept art that details the anatomy of the titular beans, and now we can never go back.
