Casey is mad about science and wants to invent an exciting room redo for his old digs, but his plan is more theory than reality. So friends Laurel and Erin join designer Jordin and carpenter Ginene to concoct some design experiments of their own and create an ingenious "mad scientist" room for Casey — complete with a new microscope and telescope, beakers, jars and cool lab stuff for his desk, lab coat curtains on his windows and his very own time machine bed! Let's hope no one gets zapped back in time before the room is finished!

Laurel's old room is in desperate need of a makeover that will match her artistic style. So her brother Julius and friend Casey team up with designer Scott and carpenter Barte to transform her bland bedroom into a wonderful world of art. Now Laurel can express her creativity in her new "artist's studio" room — with her very own potter's wheel, a drawing and crafting worktable desk that doubles as her bed, and a cool digital camera and printer for her favorite photo masterpieces.
