An old riddle. A glowing trail. A treasure worth more than gold.
 
When Danny the Mighty Diver visits Mimi in Longboat Key, he discovers a mysterious bottle buried in the sand. Inside is a riddle about the “Treasure of Turtle Bay” — and a clue to follow creatures that light the way.
 
With Willy the orca, Bruce the shark, Dobo the dolphin, and his pup Whooffie by his side, Danny dives into an ocean adventure full of glowing jellyfish, talking parrotfish, and a wise Guardian with a challenge to solve.
 
But the greatest treasure isn’t what Danny expected — it’s a mission to protect life in the sea.
