Arthur and D.W. look for a place to cool off and end up going to (the boy that kissed D.W.)'s house and learn that Molly lives there too. Molly makes many attempts to not let Arthur into the pool, but they all wind up becoming friends. When Muffy sees them shaking hands, she goes ahead and blabs to everybody that Arthur and Molly like each other and Binky, Rattles, and gang go to stop them from possibly becoming boyfriend and girlfriend!
