Summer is technically over, but that doesn't mean we have to abandon playing in the pool. In fact we could take a lesson or two from this baby hippo, who was filmed swimming "boisterously" in the hippo pool at the San Diego Zoo.

According to the video description, Devi is five months old, and ever since she was born on March 23 is now "completely comfortable with using the deepest part of the pool, where she can practice her newly learned maneuver: a 'barrel roll.'"

Although Devi is still nursing, she is starting to pick up and mouth food that her mother Funani is eating.

Play on, Devi. Play on.
