As the rollerskating rink Skate Ashbury is closing soon, Milo trains Martin and Brigette for their last chance to win the Roller Disco Dance Competition and fulfill one of their lifelong dreams. Meanwhile, Cavendish and Dakota have to try to pilfer lawn gnomes from a rather persistent old lady.
Martin and Brigette learn that their favorite roller skating rink is closing. They tell their children and Doof about their failed dream to win a contest their due to Murphy‘s Law forcing them to simplify their routine to the point where it was basically nothing. Milo agrees to train them for any situation. The night of the competition they run into their old rivals, Pete and Tina, and become nervous. After their rivals go they are up and perform. When Murphy’s Law strikes Milo instructs them what to do. They get through the routine without injury and are cheered by the crowd and congratulated by their children.
Meanwhile, Cavendish and Dakota are assigned to take away lawn gnomes from an old woman. Whenever they try to reason with her she hits them with her cane. They try and fail numerous times before retreating, but the old woman chases them. She gets out of her car and lunges at the van. They crash the van and she still comes at them. She stops when Cavendish offers to buy them off her and she agrees. Back at their base Bob Block congratulates them and tells them that gnomes are really compacted alien poop that they dump on Earth when they finish up in the bathroom.
