Grab your crayons and dive in! Join Captain Fin and Barnacle Bill on a treasure-hunting adventure across the reef — from a mysterious map and a rusty shipwreck, to a wobbly coral bridge and a very grumpy guardian crab. Along the way, they'll meet new friends like Nibbles, Ollie, and Shelly, solve tricky puzzles, and discover a legendary glowing pearl that lights up the whole ocean. Book 1 of the Adventures of Captain Fin series — 50 pages of bold, easy-to-color illustrations built for kids ages 6–10.
