S1, E19: After having put in a hard days work around the ship, Rob and his pals agree they need some fun time. Deciding that there’s no better place to have some big time fun than under the Big Top, they race off to the Circus Planet. However they arrive to find that all the performers are away so decide to put on their own circus. But unlike the others who can juggle, tumble and balance, Rob has no circus skills - that is until Squeak helps him realize he has an inborn ability to make people laugh. And as everyone knows, every circus has a clown! The crew is heading to the Space Fair, but their mission gets derailed when they find Squeak all dirty. The others take him to the Clean Up Planet to clean him up. However, they accidentally break the cleaning machine and not only have to rebuild it, but find the pieces that exploded out of it first!
