Welcome to the Underwater World! In this adventure, young readers help Molly the Mermaid organize an underwater concert. Each puzzle has three things to search and find, and there's a fishy friend to spot on every page! Puzzle Adventures combine an exciting adventure story with an important feature: the reader doesn't need to use a pen to complete the puzzles! The stories are based around characters that are popular for this age group: knights, astronauts, mermaids, and unicorns. Different kinds of puzzles help to develop key skills of memory, visual recognition, and deduction skills.
