Bob and the team are building a new home inside an old tower for Mr. Sabatini and his family. While collecting bricks for the job, Muck and Spud discover some old wooden pole and canvas and pretend to be knights in a jousting competition. In their game, they wind up making a mess of the job, knocking over all the bricks that Muck collected for the tower, only to discover that their knight costumes are actually parts for the new windmill! Bob has bought a new drilling attachment for Benny. Benny is desperate to try it out so Bob promises he can as long as he's with him to help. But before they get to use Benny's new drill, Bob gets called away. Looking for something to bash, crash or smash, Benny causes rocks to fall and winds up trapping himself. But will Benny discover something that makes all his trouble worth while?
