Bob finds that his team can do anything they set their minds to, after they build a school, a new visitor center, and finish Bob's workshop!

When an old castle needs repairs, its Bob and the gang to the rescue. Unfortunately Bob's father gets accidentally put in charge, which results in one disaster after another and he becomes a bit of a royal pain. He locks himself and Bob in the dungeon and ends up getting himself mysteriously lost in a maze. Finally a medieval pagent celebrates the castle opening and a great father-son relationship.
