Willie and Waylon are raccoons. They're also brothers. Willie is a "hold my beer and watch this" type of raccoon. It's Waylon who has to get him out of his messes. In this case, the insane Willie decides to swim in the pool. Waylon drags him out when he manages to get to the edge.
Willie is alive--for now. Eventually, Waylon won't be there to save him.
