Night at the Museum

Night At The Museum

Jedediah is a cowboy in The Hall of Miniatures. He and his men capture Larry after he is hit by miniature darts fired by the miniature figurines from the Mayan diorama. After the Politician there spoke of their dioramas getting locked up at night, Jedediah tries to split his head with a train, but fails as the train is only a miniature. He tries to shoot Larry in the eye, but to his embarrassment, his guns don't work. He fights with Octavius in the beginning of the film. After Larry is rescued by Theodore Roosevelt, Jedediah states that he won't protect him forever.

During Larry's second night working as a security guard, Larry grabs Jedediah and Octavius in order to keep their dioramas from feuding. Larry tells them that they better behave or else they will end up like their "friends" from the Mayan Diorama (which Larry previously locked up). This doesn't work when Dexter steals Larry's keys again and releases the Mayans resulting in all three dioramas ending up in a feud.

When it comes to reclaiming the Egyptian Tablet from Cecil Fredericks, Gus, and Reginald, Jedediah and Octavius end up becoming friends.

He is thought to be dead when the car he and Octavius are driving gets thrown into a snow bank thus exploding, but is shown to be alive later on.
