Mansell Monkey is a monkey who wants to be invisible. After being invisible, Mansell confessed that he told everyone that he could ride a bike, but he doesn't know how to. He wanted to be invisible to hide from his friend and teammate, Peggy Porcupine. Mopatop helped Mansell learn to ride a bike and soon Mansell is able to ride without Mopatop holding on to him. After becoming visible again, Mansell goes off to join his teammates in the race.
