This creature is a character from The Nightmare Before Christmas. He is a citizen of Halloween Town. Unlike The One Hiding Under Your Bed, The Stairs Monster makes more than one appearance in the movie. He has banded kraits as his fingers, four on each hand, and a single spider on his head. He has a small forked tongue, tiny teeth, and the area around his mouth is colored pink. Unlike most Halloween Town characters, he has no feet. Instead, his body slims down on a board with wheels attached.In his first scene in the movie, his spider hair is strewn about on his face, but for the rest of the movie, it is neatly combed.
The creature first appears in the song, "This is Halloween". The creature was later seen in the scene where the citizens are in the town meeting. The creature starts to whistle at Jack when the crowd is cheering. The creature later reappears in the Making Christmas scene, where he stocks up presents. Then, the creature was with the crowd sad after Jack was shot down. After that, the creature takes a nap when Jack battles Oogie Boogie and later wakes up after Jack comes back.
- The monster who hides under the stairs bears a striking resemblence to the Sandworm from Tim Burton's Beetlejuice, as well as Claws Ward from Monsters, Inc.
