Santa's sleigh with reindeer or horses.
The sleigh can be built without reindeer or not in the air, the sleigh has chests to represent gifts
The reindeer are tied to the sleigh with strings
The sledge from close
Another idea for people who don't like the reindeer: (it needs cheats though)
with barriers (give @p barrier) you can make horse boxes in front of the sled, maybe the horses still leash or even with thread, that's up to you. I have now times only 2 horses spawned, out of laziness xD. It is important that the barriers are 2 blocks high, otherwise the horses run out.
