Sports guru Skye Sampson asks Bob to build a 100 metre zip-line for her new fitness program. It's a job that Leo should love to help with, but he seems very distracted. Leo is put in charge of finishing the launch platform and fixing the zip-line, but he keeps making mistakes and wonders if he is up to the job. Lofty tries to convince Leo of how well they're doing, but when the zip-line comes loose it's the last straw. Leo says he should give up being a builder. Scoop and Lofty panic that Leo is going to leave the team - they decide they must make things right! But in their attempts to fix the platform they end up demolishing it instead. Bob discovers that Leo is worried that he's failed an important college test, but Bob reassures him that it's study and practice that make a good builder. Together they come up with an alternative plan using the platform debris, and build a log-staircase against a tree creating a longer and more thrilling zip-line.
