Reindeer

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

''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.''
