For this piece, we see Millie Hughes (one of the Gazonga Girls) running along the beach; gleefully attempting to get the attention of someone both far away and off screen.

Also, I would say that she's wearing an "itsy-bitsy, teenie-weenie yellow polka dot bikini", but technically it's not polka dot (nor itsy-bitsy or teenie-weenie for that matter). X3
