The Knights of Can-A-Lot, (also known as The Knights of Fix-A-Lot for American audiences), is the second Bob the Builder special released on Video & DVD on March 11, 2003 in the USA and March 28, 2003 in the UK.
Bob the Builder's dad comes to town. But when an old castle needs repairs, it's time to call Bob the Builder! Unfortunately, a case of mistaken identity puts Bob's father in charge, resulting in one disaster after another. Meanwhile, tales of Camelot inspire Bob's noble crew of machines - Sir Lift-A-Lot, Sir Roll-A-Lot, and Lady Mix-A-Lot - in their quest to get the job done, while Sir Spud-A-Lot finds a suit of armor and a fiery steed almost perfect for jousting! Back at the castle, Bob's father is a bit of a royal pain when he locks himself and Bob in the dungeon, then finds himself mysteriously trapped in a maze! Can they be able to get out?
