Presenting what is very possibly the laziest chess design ever conceived: Pawns with Hats! Is it a suggestion that we're all the same inside, and the king is no different from the pawn? Is it some variant of the idea that a person might "wear many hats," referring to the various responsibilities we burden ourselves with in our daily lives? Is it a Team Fortress 2 reference gone horribly, horribly wrong? You decide!
This is the rook. That's not really a hat on his head; he just doesn't know what stools are for. Nobody tell him.
All pieces:
