Behemoth is a large man wearing overalls and an axe in his head. He rarely talks, and it appears as though his head injury has caused some brain damage.
May also be known as the Farmhand. It's on the list when Jack is handing out jobs for Christmas.
The Nightmare Before Christmas
When Lock, Shock, and Barrel come back with the Easter Bunny, Behemoth loudly points out, "Bunny!" Scared, the Bunny hops back into the bag, and is subsequently (with some rather heavy persuasion from Jack), taken back to its own holiday world.
- In Behemoth's concept art, he was originally going to have a wrench or a garden hose stuck in his head.
