"Heidi Klum doesn't make house calls," designer Kate Pankoke tells the camera. "This has to be something big."

The challenge -- the second unconventional one this season -- takes the designers to Coney Island. Working in teams of two, they must win their materials by playing tried-and-true carnival games.
