Reindeer

The Reindeer of Halloween Town were created by Dr. Finkelstein for Jack to use during Christmas time. Santa Claus also has his own set of reindeer, which these ones were based off of, although, these ones are made out of the skeletons of reindeer instead.

The Nightmare Before Christmas (1993)

''A special set of Halloween-styled reindeer, custom-made by Dr. Finkelstein for Jack. They're just right for pulling Jack's coffin sleigh through the Christmas Eve sky.''

Kingdom Hearts II
The reindeer plays a little role in Christmas Town. They are only seen twice, once with Santa Claus, and once with Jack Skellington.
