And drive rocks like they're cars (while at the same time being unable to drive the in-universe equivalents of cars that operate on similar controls), and create a pizza box simply by mashing a bunch of burgers into a pizza, and have flies, gorillas, and cockroaches be able to breathe underwater.
This is interesting, because it used to be a sort of meme going around that Rudolph and the rest of Santa's reindeer were actually all female due to male reindeer shedding their antlers in winter while the females retained theirs (shedding them in the spring). Of course, real reindeer of either sex also don't fly or look like white-tailed deer, so we probably shouldn't try to apply actual biology to Santa's special reindeer.
