Every once in a while, the concept for a project comes together so well it's like it built itself. This grinning guy is a visual pun. Dressed up for tonight in a cheap mass-market skeleton costume, he references classical white-on-black skeletal drawings made since the 1800's. Pterosaurs across the moon replace the sterotypical bats. And what kind of Jack-o-lantern would a dinosaur carry? What is the right size, the right shape, the right color, and has the right carrying capacity for meat treats? An ammonite, of course!
