"Yellow and Fuzzy lift their shovels to start building a sandcastle so tall it will reach the sky. Floppy and Calico are ready to mold the towers. Big Brown Bear helps them pack the sand tightly--but still the towers collapse when the buckets are overturned. Oops! The sand is too dry. What will happen if they move really close to the water?"--Publisher marketing.
