Reindeer antifreeze

Mosses are important to creation as a whole in many ways. They provide a place to live for many tiny creatures, and they are useful to birds for building nests. Most animals don't usually eat moss, because it does not have a lot of nutritional value. However, some animals such as bears, deer, and turtles will eat it if they can't find any other kind of food. There is one animal, however, that eats it regularly: the reindeer. Reindeer live in cold climates, and moss has a special chemical that helps keep the fluids inside the reindeer from freezing, even on the coldest of days. Moss, then, is a kind of reindeer antifreeze.
