Spy-fan brothers Dylan and Hayden want a playroom fit for a secret agent. So friends Alex and Rachel accept the mission and, with the help of designer Scott and carpenter Barte, transform the boys' plain playroom into a "high-tech spy penthouse." This top-secret hangout would make even James Bond jealous with its cool gadgets and sleek glass-door silhouettes, couches that turn into beds, covert spy camera and a top-secret entertainment center that goes from a fireplace to a TV at the touch of a button.

Sisters Alex and Rachel want to give their dark basement playroom a workout. So friends Dylan and Hayden work up a sweat with designer Jordin and carpenter Ginene to turn the girls' drab pad into a high-class "health club and spa." Their amazing new space comes with its own smoothie bar, a spa menu featuring the boys' homemade granola, and kid-sized exercise equipment. And, after a tough workout, the girls can sit back and relax in their very own massage chairs!

Plus, watch as both teams battle their way through gobs of goop to win a chance at the Labor Savers work crew or a mysterious clue about their room on the new, improved and downright messy Boys vs. Girls challenges!
