Here's a wave-washed beach where a castle can stand! Where are the bears to build on the sand? Whee! 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? With Shirley Parenteau's rhyming verse and David Martin's irresistibly cute illustrations, little readers are invited to join the bears for some trial and error-and creative cooperation-on a perfect day at the beach.
