We may have grown older, but we'll always have a soft spot for Grover and the hit book from our heyday, The Monster at the End of This Book. First published by Sesame Street in 1971, the book now takes a modern twist, with Grover asking for your help to turn the pages (except for the part where he wants you not to turn the page, and then kids can help break down a brick wall and more by tapping on the screen). Of course we know how it all ends, but like life, most of the real fun happens along the way.
