Bert and Ernie's Great Adventures: Treasure Hunt is a musical sound book that invites children to join Bert and Ernie as they search a deserted island for buried treasure. Children ages 3 to 5 can enjoy pressing buttons to hear sounds as they read the engaging story about some of their favorite Sesame Street characters. Illustrated icons on the book's pages match seven buttons on a panel attached to the book. As readers and pre-readers follow the story, they can find the matching buttons and press them to hear the sounds of the Sesame Street characters' island adventure. Each button plays one of these sounds: bull; Bert and Ernie's pirate anthem bull; A creaking treasure chest lid bull; The popular kids' song "Sailing, Sailing" bull; A crash of lightning, signaling an approaching storm and an end to the Sesame Street friends' adventure bull; Chatter from Bert and Ernie's new monkey friend bull; Bert's playful tune as he navigates his friends safely off the island The book's extra-thick, coated pages help prevent rips and tears. Three replaceable long-life AG-13 button cell batteries that power the book are included. Bert and Ernie's Great Adventures: Treasure Hunt conforms to the safety requirements of ASTM F963-08. The book has been safety tested for children 18 months and older.
