The revolutionary, patent-pending sand toy has children put their imagination, creativity and problem-solving skills to use in constructing up to 64 different sandcastles. The 12-block building system of interchangeable "mold blocks" creates 8"-high columns of sand by adding wet sand to the interior compartments of the blocks and then removing them to reveal sand sculptures. The toy combines elements of art, a three-dimensional puzzle and construction. Launch date: July 2008.
