Imaginations are let loose in this challenge where teams must create an evil lair for a supervillain Minifigure in 13 hours, including a vehicle. The least impressive villain world will ultimately send its makers home.

The four remaining teams each contribute to a Time Train diorama built in 16 hours. From the Wild West, the Future, Prehistoric and Medieval Times, this challenge will mark the end of one team's journey and reveal our grand finalists.
