This Is What Hippos, Puppies And Walruses Look Like When They Sleep

Good night, hippo!

What's cuter than a walrus snoozing in the ocean? A pile of walruses snoozing on a beach, of course.

In the video above, National Geographic takes a look at many different types of animals -- bats, hippos, puppies and more -- and observes how they sleep. Alongside truly adorable footage, Nat Geo added fun sleeping facts to show just how certain animals sleep standing up, upside down or bobbing up and down in the water.

If you need to add any more cuteness to your day, check out these photos below of big animals settling down for some sleep:
