In honor of World Elephant Day, we dug up this video of baby elephants romping around in the pool. These two little guys, Baylor and Tupelo, have their very own pool at the Houston Zoo. The pool only lasts about five uses before it has to be replaced. This might have something to do with the fact that Baylor weighed about 1,100 pounds and Tupelo weighed a little more than 600 pounds at the time!
