Incorporate cutouts of colorful fish, friendly dolphins, mermaids, and even a friendly octopus around the perimeter of the pool.

For activities, organize a ‘treasure hunt’ for weighted ‘gems’ or ‘pearls’ at the bottom of the pool. Play a game of ‘find the Dory’ with plastic fish hiding around the party area.
