The Crew Builds a Roller Coaster/The Crew Builds Motor a Play Space. Mr. Ducky-Doo and Mr. McTurtle are having a playdate! But when Speed Meister builds them a roller coaster to ride, his shoddy construction accidentally sends them rolling out of control all over Builder Cove! Rubble & Crew jump into action to chase down the pet pals and bring the runaway roller coaster car to a safe stop. Finally, the pups work together to save the playdate by building a new roller coaster that's bigger, better, and safer! // Rubble and the crew are on their best behavior because today's the big Bark Yard safety inspection. But when Motor goes boom and makes a mess in the Bark Yard, the pups enlist the help of Coach Karima! Together, they find a construction solution to let Motor keep playing, while keeping the Bark Yard safe and clean. But will they finish in time to get a gold safety star from Inspector Inez?
Rubble moves with his family of construction pups to the nearby town of Builder Cove where they live, play, and build whatever the community needs.
