The Monkey is one of the residents of Isla de Corales. He used to be a leader of a pack of monkeys on the
island, but was kicked out. He wounded up at a bar and people kept buying him drinks. He got mad when he and a group of people in the bar were watching an interesting sports channel when Manny suddenly takes the remote and he puts on the cartoon he likes, and throws the TV remote into the water. He was also one of the people in the crowd who stampeded into the Wild Side after Greg Heffley accidentally broke down a part of the wall.
