Fun in the bathtub or the pool just got an upgrade, all thanks to the Banzai 4 pc. Water/Pool Toy Dive Set. Toss the mermaid dolls into the pool and lake and see how many you can grab before they reach the bottom. Challenge your friends to see who can be the fastest and collect the most mermaids. This pool toy set is great for helping to develop swimming and diving skills. The mermaids' bright colors are easy to spot underwater.
