Nandi the elephant resides at the Reid Park Zoo in Tucson, Arizona where she is one of the youngest elephants.
The little calf is too small to play with the bigger guys but not willing to have her miss out on the fun, the zookeepers provided her with a special mini pool, complete with a toy ball.
Her splashing and thrashing around is proof of how unreservedly happy she is and this has made it right to the top of our list of favourite animal videos.
