Usually Percy prefers rivers or lakes instead of public pools, but sometimes he gets in the mood to go swimming when he thinks he can make a new friend of two. As was the case here! One rather hot day in the summertime, there were many kids at the pool to cool off and have fun. Percy decided to join in, and ended up spotting someone who looked a little nervous to get in. Being an expert swimmer, himself, he decided to take it upon himself to say hi and keep them company. Perhaps he could also try and convince them to join him in the pool?
