The Monster At The End of This Book, and "Would You Like to Play Hide & Seek in This Book With Lovable, Furry Old Grover?"

These two books are hilarious (for adults and kids) — we mean laugh out loud — especially if someone in your house has mastered imitating Grover’s bouncy and “gurgley” voice. Our kids have absolutely loved these stories from ages 2 through 6 years-old. We’ve read them so many times that the pages are worn out. Basically each book is a hide and seek game with Grover. He paints himself, hides behind other pages and does other silly things to make himself disappear. There are other Sesame Street characters who help him out too. Very kid friendly and not a bit scary. You can regularly find these at used book and thrift stores.
