I honestly think I liked this book most for its insight into a child’s mind. Children’s minds truly work this way, they do these things and they believe that there is a monster of some kind under their bed. I liked however, that there was a surprise. There was an alligator under the child’s bed, at least according to him. As an adult aged reader, that was a surprise to me, but to a child reader I bet this was no surprise at all, of course the alligator came out to get food! Obviously, due to the ...more

So darn cute! I loved this story, the sweet and humorous illustrations, and the resourceful kid who solved the problem of that pesky alligator under his bed--all by himself! It's just darling.

Of course, I'm a grown-up and no alligator has lived under my bed for quite some time so this book did not scare me at all and I think it's a good one for helping to overcome scary nighttime imaginings :-) But, some children may be frightened by it, see this fine review for example:

Cool illustrations, but I think a kid could get scared reading this.

I like Mercer Mayer's stories and this has a catchy title, so we checked it out at the library. I think it actually scared our 6 year old, but I was able to convince her that there are no alligators in Hawaii, so it wasn't overly traumatic. Not sure if this is the best story to read to younger children!
I love monster-themed picture books, but for some reason this one just didn't really do it for me. I guess the idea of the monster being real wasn't surprising to me, and it also wasn't charming. I don't know. Just not my thing.

Yet another book aimed at instilling fear in children.
Sure, if you've already taught your kid how to be afraid of "monsters" in their room then I suppose this is a good book for them.

Unfortunately the book also tells your kids that it's ok to take all of the food out of the refrigerator and strew it along the floor, enticing the monster out of their room.

If you've made your kid THAT anxious, then probably this would be a good thing for your kid to read/do.

I liked this book as a kid because I could relate to thinking there was a monster or something under my bed. The author does a good job getting in the mindset of a young boy and what he does to avoid the alligator. He even put a wooden plank going up to his bed and overtime he tried to look at it, he would hide and his parents couldn't see him either. He grabbed some food and put it in the garage and a trail going to his bedroom. When he ate the trail and went into the garage, the little boy ...more

When I was young, I always thought there was an alligator in our bathroom. I always thought it would jump out of from water and snapped. But fortunately, it never happened. Lol
So this book got me. He even safety put the alligator in the garage. Nice job!

There's and Alligator under My Bed, by Mercer Mayer, is a story of a little boy who knows there is an alligator hiding under his bed. He has not seen it, and neither has his parents, but he knows without a doubt that it is there. One night he decides to lead it away with food and traps it in the garage for his dad to find in the morning.

The illustrations were very simplistic sketches, but most everything had very soft edges. For example, there is not use of black in the story, everything is made

The common childhood fear of having some sort of monster or animal under the bed comes to life in this story by Mercer Mayer. The main character believes there is an alligator living under his bed, but whenever his parents look it hides, so he has to take measures into his own hands. He laves a trail of bait into his garage, and watches one night as the alligator follows his trail, and he traps it in the garage, and finally he makes sure to let his dad know to watch out for the alligator the ...more

You can see the author/illustrator reading his book, with pans of the illustrations, here:

This is a twist on the monster-under-the-bed scenario-- a young boy is convinced that there is an alligator living under his bed, but when his parents look, the alligator hides somewhere so they don't believe him. He comes up with a plan to lure the alligator out from under his bed: he places a trail of various kinds of food from his room down to the garage, and when
So even though I've technically never read this book until now, I still consider it a book of my childhood. Because there's a story behind me and this book. When I was in kindergarten and they had all these books they were giving away at the library, they talked about a couple of them beforehand--this being one of them. I remember really, really, really wanting to get my hands on it badly. Well, sadly some other little girl got it before me, and there were no more copies. I'd cried about it and ...more

This book follows a boy who finds an alligator under his bed. He gets scared, so he calls to his parents, but they do not believe him and tell him to go to sleep. Since they do not believe him, he takes action into his own hands, and thinks of a way to get rid of the alligator. He gets food from the fridge that the alligator likes, and makes a trail of it to follow to the garage. The alligator follows the trail and get locked in the garage, and the boy writes a note to his father, telling him ...more

This was one of my favorite books growing up. I really enjoy this book because it's very simple, and surrounds a common childhood fear of monsters under the bed. As an older, that was a surprise to me, but to a child this plot was no surprise at all, of course the alligator came out to get food! Obviously, due to the assignment this is a primary age appropriate read. The vocabulary is not particularly difficult, and there is only a small amount of text on each page. The illustrations reminded me ...more

The story "There's an Alligator under my Bed", by Mercer Mayer, is about this little boy that thinks that there is an alligator that is trapped under his bed. When he calls his family into check under the bed they couldn't see any alligator. At the end of the story he finds that there wasn't an alligator under the bed.
The theme for this story is innocent, and happiness. I loved that the boy is so relatable to so many other children in this world. When I was a child I was always afraid that some

In the book, There's An Alligator Under My Bed by Mercer Mayer, it's about a little boy who is not your normal little boy. He doesn't think there is monsters in his closet or under his bed. But, he thinks there is an alligator lurking under his bed. He jumps into his bed trying to make sure that his feet don't come close to the alligator and even begs his parents to look for this creature. Of course the parents don't see the alligator and he decided it was time for himself to get rid of it. He ...more

There are books from your childhood that are indelibly burned into your imagination... and Mercer Mayer's There's an Alligator Under My Bed is one of those books for me. The story of a boy planning to lure out the alligator from under his bed is coupled with illustrations that I can recall with near perfect clarity. Perhaps it's because I never found the generic "monsters" genre to be all that scary, I appreciated Mayer's alligator substitution. In addition, Mayer provided a practical plan for a ...more

We picked this book up at the library because it was a classic that we needed to read. It was a cute book about a boy who thought he had an alligator under his bed. But every time he or his parents checked, he couldn't find it. He came up with a plan to draw the alligator out and in the garage.

It was a cute book and my daughter loved the illustrations of the alligator. I thought the last page with the note to the boy's dad was really cute. The reader doesn't really know whether there was really

I should give this book a 5 for my grandchildren; it has been their most requested book at the turning 3 stage, though I certainly don't find it as enthralling as they obviously do. It bothers me some that they don't understand that there really ISN'T an alligator under the bed! They show me, "there he is!" but he seems like a fairly decent kind of guy and nothing bad happens, so I'm guessing they are using this book to approach the usual childhood fears of the dark and of what's under the bed. ...more

This is a book about a boy who thinks there is an alligator under his bed. No one is able to see the alligator but him. It is a good book to prompt discussions about being alone and being afraid of the dark. I think this a cute book to teach cause and effect as the main character "lures" the alligator by using food and candy from his room to the garage. I think children will find the illustrations entertaining. Classroom discussions can involve the applications of what the boy has done (lure the ...more

We own There's an Alligator under My Bed. My aunt and uncle bought it for Christopher at his (my?) baby shower. I'd never read it before then, but it's become one of my favorite childrens' books over the year.

It's about a boy who's scared of the alligator under his bed. His parents can't see it, so they don't offer any help. It's up to him to take care of the problem! I love his solution. The words are simple, the illustrations are wonderful, and the resolution is great. We read this book over a

This cute picture book is a story about an alligator who lives under a young boy’s bed. However in this story, the young boy is the only one who can see him. He tries to tell his parents but they don’t believe him. After his parents fall asleep, the boy “lures” the alligator out from under his bed with snacks and a trail of food that he think it may like all the way to the garage. As planned, the alligator eats the trail of food and ends up in the garage where the boy locks the door. Then the ...more

There's an Alligator Under My Bed by Mercer Mayer, is an awesome book that all my children love! We read this book together before bed and all my kids thought it was funny. A little boy thinks there is an alligator under his bed. He knows the alligator is there, however, when he looks its always hides. So instead of being afraid, he is brave and lures the alligator to the garage! This book can be for bravery or touch on imagination / imaginary things. I personally loved this book, as well.

A cute story about a little boy who has an alligator under his bed, and how he gets rid of it. Very cute. I love the Alligator's mischievous expression when he is peeking out from under the bed.
My little girl (age 2) enjoyed this one. I was worried at first that maybe this would cause her to be afraid of something under her bed, so when I read it to her I would say things like "silly alligator - he's hiding under the bed", "see how he is laughing and playing hide and seek?"; so now my little on
