The Nightmare Before Christmas
Three skeletal reindeer acted as the reindeer that pulled Jack's sleigh when he made his journey around the world to deliver gifts for Christmas in place of Santa Claus. They were broken when the military shot down Jack's sleigh with their artillery.
Kingdom Hearts II
The Skeleton Reindeer make an appearance in Kingdom Hearts II of the Kingdom Hearts series of videos games made by Disney and Square Enix. They are seen when Jack lands his sleigh back on the launch ramp to greet Sora, Donald Duck, and Goofy, welcoming them back to Halloween Town and wishing them both a Merry Christmas and a Happy Halloween. As Jack mentions how he is heading to Christmas Town to see Santa, Sora, Donald, and Goofy look around at the Halloween-themed Christmas decorations, before looking at the Skeleton Reindeer, who look at them and let out a creepy laugh or squawk, unnerving Donald and Goofy, but leaving Sora excited to meet Santa.
