Blue's friend Green Puppy is over visiting with Blue at the Blue's Clues house and we're all having fun with blocks. Steve & Blue constructing towers with our help and Green Puppy knocking over towers of her own. We learn about concepts such as balance, shapes and as we construct. A Skidoo segment offers a look into architecture. We help an architect to select shapes to build various structures based on blueprints that he's created.
