The ultimate challenge comes to life when the contestants are blown away to discover it's all about Star Wars! Not only do they get to build their favourite ships but are thrilled when a new Star Wars LEGO Brick Pit is revealed.

In the penultimate episode, teams are facing two challenges, the first one sees them only able to use pieces from a smashed LEGO Harley Davidson. In the second challenge they must create a building that works in both day and night.
