Santa's Workshop

This structure spawns in snowy biomes. It's a building with a sleigh parked next to it, plus a stable where you'll find a brand new mob: the Reindeer. You can actually tame these flying reindeer, and use them yourself. If you feed them wheat, you can use a lead to take them to the sleigh, then right-click to tie them to it, then all you need to do is get in the sleigh. Now press the button and you'll be up, up and away! If you go inside the workshop, you'll find three other new mobs: Santa Claus, Mrs. Claus, and Elves. The elves are passive mobs, and you can often find them building toys and wrapping presents. Mrs. Claus is passive too, and is found wandering around the area. Santa Claus is a neutral mob, meaning he'll attack you, but only if you attack him first. He also attacks you if he catches you harming an elf, Mrs. Claus, or a reindeer. On Christmas Day (in real life), you can find the elves loading up the sleigh with presents, with Santa waiting patiently next to it. If you try to steal the presents though, Santa will attack you. On Christmas, if you go to sleep inside a house (the game will recognize a house as any size 3x3 or larger foundation with walls and a ceiling, it doesn't matter if you have windows or not) that has any type of tree inside of it, Santa will come. When you wake up, there will be presents underneath the tree. There's usually some pretty good stuff inside, but if you've attacked any passive mobs in the past 25 Minecraft days, you'll get coal.
