This 1971 Little Golden Book was a staple of my childhood. In 1996, that little punk Elmo horned in on the spotlight in the sequel, Another Monster At The End Of This Book. The same plot, but twice as much furry cuteness.

*** Spoiler Warning ***

It seems that there is a monster lurking at the end of the book, and Grover pleads with the reader not to go further. Despite Grover’s frantic pleas, the pages keep turning. Grover resorts to tying the page down, boarding it up, and building a brick wall, but nothing can stop the omnipotent reader. Finally, the reader discovers that the monster is furry, blue, and lovable – Grover himself. Now the kids are off to a nightmare-free sleep.
