I have been reading Mo Willems’ books for a long time and I have recently stumbled upon his book called “Leonardo the Terrible Monster!” “Leonardo the Terrible Monster” is a children’s book by Mo Willems which is about a small monster named Leonardo who tries to be a scary monster, but cannot do so effectively, so he tries to find a child that he could easily scare. “Leonardo the Terrible Monster” is a truly brilliant book that children everywhere will easily love for many years!

Another love for us. Besides the fact that it's from one of our recent favorite authors, Mo Willems, the story kept the attention of my 5 yr old and preschoolers both. The pictures were cute and big, always good for a group of kids, and the idea of scaring was fresh on our minds as we've recently seen Monsters University, the movie. Maybe a level 1 reader book for young readers. Overall, it was much enjoyed.

Another winner from Mo Willems. The fun "twist" that is explained right away is that the featured monster is "terrible" AT being a monster; he can't frighten anyone! Full of fun and "ferocious" monsters, this book is at heart a story of honoring yourself and being grateful to those friends who help us do so.

Leonardo is a terrible monster - he's just not scary enough! He finds a scaredy-cat kid to frighten, but ends up with a friend instead.

Who can resist Mo Willem's charms as an illustrator? With a few simple lines, he gives us Leonardo, a monster who teaches us both meanings of the word terrible. Instead of being scary-terrible, he's just terrible at being a monster. Leonardo is perhaps the most adorable and amusing monster in fiction, but he longs

Short & sweet, with both Leonardo and Sam perfect representations of what it feels like to be a little kid. Also, gotta love books with good characterization, fun word choices, and true narrative arcs, that aren't too long for storytime.

My favorite part was Caitlin reading the book to us in class. :)

What inspired me was the lesson learned about how to be a nurturing friend.

After we read "Don't Let The Pigeon Drive the Bus," I knew that I had to read more of Mo Willems' work. I loved the way the illustrations in his book seem simple, but manage to include lots of things that complement the words on the page. I also think his books have some of my favorite "page-turns."

The title character in "Leonardo, The Terrible Monster" has a serious problem. Well, it's a serious problem if you're a monster: he just isn't thats scary. Unlike some of the other monsters, who have

Leonardo, the Terrible Monster by Mo Willems tells the story of a very young monster who is terrible at being a monster, because he can't scare anyone.

Leonardo wasn't big, didn't have hundreds of teeth, wasn't weird and
just wasn't scary. Leonardo researches until he finds the most timid boy to scare: Sam. He works hard until Sam cries. When Leonardo celebrates having scared someone, Sam tells Leonardo all the troubles that made Sam finally cry, including not having any friends. Leonardo makes

Oh my word. This comes at the perfect time--when I need one more, quick read for the big Halloween program. And this is excellent! Must practice.

10/30/10 This was fabulous. I loved reading it over and over as I practiced. And I loved reading it to the audience. I think they enjoyed it, too (judging by their faces and the little comments I heard).

What would I do without Mo Willems?

This is a cute book about a monster, Leonardo, who is terrible at being a monster; he can’t scare anybody. So, he does his research to find the one kid (named Sam) who he’ll be most likely to be able to scare, and goes to do that. After his attempt, he ends up changing his plans. It was very predictable (for this adult) but it was sweet.

This is a good book for young children, with very few words on all pages except for one double page spread where there are a lot of words, and in a color a bit h

My 5 year old could not stop laughing at Sam's teary outburst, and has now taken to saying "I am going to scare the tuna salad out of you!"

Another gem from Mo Willems!

Leonardo was a terrible monster. He simply could't scare anyone no matter how hard he tried. One day he decided to search for the biggest scaredy-cat kid. He snuck up on the kid and tried to scare but also failed. The boy was already having a bad day. Leonardo made the decision to cheer him back up again, and they became the best of friends.

This book I believe is a great bedtime story. I like being in perspective of the monster. The author used a great deal of facial expressions. Leonardo showe

This is a great story about a little monster who can't seem to scare anyone. So he researches the biggest scaredy cats in the world and finds a perfect little boy to scare. But he finds out that, while he might not be very good at scaring, there is something he is good at. It's a fun story to read aloud, and the pictures are very simple, but expressive. Our girls really enjoyed this story.

Leonardo is terrible at being a terrible monster. He cannot scare anyone. He goes on the search for the most scaredy-cat kid...will he be able to scare him?

I borrowed the CD from the library which features Mo Willems narrating the story. His voice had my son and I rolling on the floor with laughter. Great message, great illustrations, great delivery, great book!

This book would be good to talk about how people feel when you scare them. It could be good for April Fools Day or Halloween. I like how he decides to befriend the character he scares, but continues to scare him occasionally. The page where his friend yells can be difficult to read, but it visually serves its purpose of showing how much emotion his future friend put into the words. I feel like a lot of my students would be able to relate to the monster. I would have them write or show about a ti ...more

What a surprise. The terrible monster turns out to be TERRIBLE at being a monster (typical Mo humour)! And this monster couldn’t scare anyone!

He didn’t have 1,642 teeth like Tony. He wasn’t big like Eleanor. And he wasn’t just plain wierd like Hector.

What’s a poor creature to do? Simple. Find a scaredy-cat kid – and scare the tuna salad out of him! (Mo’s words, not mine.)

So there he is: moony, sourfaced, unsuspecting Sam. Is Sam the perfect candidate? Leonardo is about to find out and the ending

Ha! It was rather amusing reading this. The kid's name was Sam, which so happens to be my name. I also wear glasses just like he does. I related to it even though it was a children's book. My son had a blast reading it, and I think that that's all that matters to a parent.
Cheers and Happy Reading Kids!

This book is a fictional book. It currently does not have any awards. The book is about a little monster named Leonardo and he really wants to scare someone. Through the whole book he is unable to scare anyone until he sees a little boy alone who he sneaks up on and scares. In the time he boy is scared and begins to cry and Leonardo learns that’s scaring people should not be his main concern and he should not be trying to scare people because it only hurts their feelings in the end.

Leonardo is a terrible monster. Terrible at being a monster, that is. In this story, poor Leo can’t win for losing… until he finally changes his approach. It is a sweet story of the all-too-familiar social struggle of trying to fit in but in the end, Leo does and makes a friend to boot!

Mo Willems delivers another solid, lovable book for young children to enjoy. His books tend to stay within the Sesame Street age range and feel which leads me to give it more of a 4-star rating but, nevertheless,

Leonardo is a developing character in this story. Leonardo starts out being a terrible monster and not being able to scare anyone. After many failed attempts, he tries to scare a little boy named Sam and makes him cry. Leonardo thought he became a great monster until he realized that Sam was upset from various reasons. After coming to the realization that he wasn't the best monster, Leonardo decided that he would be a great friend. This story is a great read aloud, especially due to the page whe ...more

This is an older book by Mo Willems, but just as delightful as always! Leonardo the monster has a terrible problem -- he isn't scary. So he searches for the perfect child to scare. I love all the research he does before he finds Sam, the perfect scare candidate. Sam ends up being a lot more to Leonardo than just a child to scare, and I love the turning point in their relationship.

The illustrations and text are a little more detailed than Mo's other books, but the backgrounds are plain pages and

Leonardo the monster seems incapable of scaring anyone. So he does his research and looks for the easiest person to scare. But when he tries to scare the boy, he instead makes him cry. The poor boy was having a very bad day. Leonardo decides to become his friend instead.
Overall, this story and illustrations are cute. The coloring and style of the illustrations reminds me of something from the 1960s so it is a little bit different. There are several humorous points to the story which makes it mo
