The neighborhood block party is today. Jada and Jamal Perkins are super excited. Their best friends, Carlita Garcia and Josh Cornell, are on their way over. Mr. Perkins promised them a BIG surprise.

Thump! Thump! Thump!

Bump! Bump! Bump!

The surprise is thumping and bumping its way around the Perkinses' backyard. What could it be? And how will the Bradford Street Buddies get a surprise that BIG to the block party?
