The story revolves around Leo, an inquisitive truck who helps his friends with various tasks. Initially, Leo assists in fixing a broken water pipe at a car wash by building a pipe-laying crane. Later, he helps the robots build a basketball pole on the playground by creating a concrete mixer. After the pole is set up, the robots play basketball.
The robots then attempt to build two castles, but they run out of blocks. Leo helps by bringing more blocks, which requires building a big truck. The robots eventually finish their castles, and Leo helps a stuck yellow car by building a tow truck. The tow truck successfully pulls the car out, and it's taken to the car wash to get cleaned.
