Who, or what, is Wilmot?

[swarm]

When I played Wilmot's Warehouse I generally understood that Wilmot was meant to represent a person, just like all the other symbols you were arranging represented objects like footballs or upside down bananas. However, Wilmot Works It Out has shaken me to my core with the final puzzle, with Wilmot next to Sam. Questions arise. Is Wilmot a robot? Evidence suggests they consume food, though. An alien with a telekinesis and levitation abilities, perhaps? Folks write in.

He just is build like a brick, because Wilmot works (it) out.
