Spot is the pet dragon of Eddie Munster. Not much is known about him or where he comes from, but he is treated as if he was dragon. He likes to lay around the house, but his regular spot is his lair under the Munster's front staircase in Munster Mansion. Rarely anything of him is shown except his tail or head. He has a voracious appetite, eating everything from cars, furniture and man hole covers. He once ran off and got lost in the city sewer.
- According to one story, Spot was created by Fred Gwynne and Al Lewis by material on the set, but the usual story is he was created from the head of the Tyrannosaurus in One Million B.C.
- Spot was never seen whole in the series; he was only seen whole in the 2000 reboot, 1313 Mockingbird Lane.
