In the fifth episode of "LEGO Masters" Season 1, each team was given the chance to design a city block to contribute to a massive LEGO Mega City. Like in the first challenge of the show, all of the teams' builds would be lined up to become a greater whole, which made the competition for most spectacular landmark particularly fierce.
Aaron and Christian, who won the "Dream Park Theme Park" contest but hadn't seen the podium since, decided to wow the judges with the tallest tower in the city. As a result, they designed the Eco Tower, a 14-story skyscraper at minifig scale, complete with a working elevator, floor-to-ceiling windows, and a slice-of-life story told behind each pane of "glass." But after 14 hours of work, disaster struck when the tower toppled to the floor on the way to the podium for judging, destroying its top four stories. Aaron was devastated, walking off the set in frustration. A pep talk from Christian brought him back to the judging area, where he received some good news: This was only part one of the challenge.
Before judgement, each team was given four additional hours to place their city block under siege by evil forces of their own choosing. This gave Aaron the time he needed to rebuild the broken section of the tower while Christian constructed a giant monster, Smogra, to menace the city. Their finished product, "Attack on Sustainable City," was marvelous, but some pretty stiff competition held it to second place.
