Additional Details

Leonardo is truly a terrible monster-terrible at being a monster that is. No matter how hard he tries, he can't seem to frighten anyone. Determined to succeed, Leonardo sets himself to training and research. Finally, he finds a nervous little boy, and scares the tuna salad out of him! But scaring people isn't quite as satisfying as he thought it would be. Leonardo realizes that he might be a terrible, awful monster-but he could be a really good friend.

Community Reviews

I still quote this book, five years later!

This book inspired one of the favorite things that I say to my son when I put him into bed: "I'm going to hug the tuna salad out of you!"

The monster in this book goes from scaring the tuna salad out of the kid to hugging the tuna salad out of the kid. It's a very sweet story, but really, how much tuna salad does this kid eat? Someone should tell his parents that tuna can contain a lot of mercury, and I'm not talking about Freddie.

Bad Monster

My kiddos and I enjoyed this book! But we pretty much love everything by this author. Always entertaining.


Kids will enjoy this.


Would you rather be a terrible (that is, not scary) monster or a good friend? Maybe you can be both. The real difficulty would come in being a good (scary) monster AND a good friend.

Sparse drawings (very different from much of what we read these days!) and sweet story. The page where Sam just pours out all his woes is notable by way of contrast with all the rest.


Funny book -- enjoyed it.
