to the island itself, including its beaches, volcano, and jungle, with some changes for the main characters - Marina takes residence in an ornate, life-sized sandcastle evocative of the , built by Sharko; Zig and Bernie live with a cargo plane pilot in his crashed plane within the jungle; and Sharko operates as a lifeguard for the aquatic lifeforms who frequent the beaches.
