"Chuck and Dakoda are setting sail on a high-sea adventure! The boys join local legend Marco Pollo (a swashclucking rooster) on his quest for the Coral Crown, the most special treasure in the entire ocean.

Can the buccowneers work together to find the treasure before the evil Kingfish finds them?"--Page 4 of cover.
