The Once Upon a Potty Sound Book for Boys invites toddlers to join Joshua as he learns how to use the potty. Adapted from a story by children s author and illustrator Alona Frankel, the interactive sound book begins with Joshua receiving his own potty chair from his grandmother. Although he doesn t know how to use it at first, Joshua eventually learns to go in the potty every time. Toddlers will enjoy pressing the book s four big, bright sound buttons that match the illustrated icons in the text to hear: A triumphant tune to mark Joshua s success on the potty. Meows from Joshua s cat as it enjoys a bowl of milk. Tweeting birds taking a bath. The rewarding flush of a toilet as Joshua says goodbye to his Wee-Wee and Poo-Poo. The buttons and musical speaker are located on a large plastic panel anchored on the book. The buttons are accessible from every page. Extra-thick, coated pages prevent rips and tears. Three replaceable long-life AG-13 button cell batteries that power the book are included. The Once Upon a Potty Sound Book for Boys conforms to the safety requirements of ASTM F963-08. The book has been safety tested for children 18 months and older.
