Nancy, George, and Bess are headed to beautiful Barnacle Beach for a pirate-themed birthday party. They've planned every detail, from nautical party games to a real chest of buried treasure. This is going to be the most fun party ever! Until none of the guests show up. Perhaps they've been scared off by mythical beach monster Lonny the Lake Lizard. But that's just silly -- monsters aren't real, right? And now the treasure is gone! This looks like another case for the Clue Crew -- time to find the missing treasure, and the missing friends, too!Nancy, George, and Bess are headed to beautiful Barnacle Beach for a pirate-themed birthday party.
