The Underwearwolf is a clever and humorous twist on a classic movie monster. Gideon Sterer has brought to life a hilarious and furry new friend kids are sure to love.
Our main character LOVES underwear. He has a collection he is clearly proud of, so when his uncle gives him a special pair for his birthday, he cannot wait to try them on. Sadly, he does not heed the warning written on the fine print of his underwear. It devolves into a hair-raising tale about a little underwearwolf as he ventures around town under the light of the full moon.
It has beautiful illustrations, carefully crafted to delight and capture the attention of its readers. This is the kind of story that will draw the readers in, having them hanging on each page until the very end. I would definitely recommend this for anyone looking for a cute Halloween story to share with littles; it definitely has the potential to become a spooky season favorite in and out of the classroom.
Thank you NetGalley and Simon and Schuster Children's Publishing for giving me an advanced copy of this book in exchange for an honest review.

We read Underwear Wolf and thought it was absolutely hilarious—we definitely recommend it! From the very beginning, it had us laughing, and honestly, we didn’t want it to end. We are already hoping there will be another book so we can find out what Underwear Wolf does next!
One of our favorite parts was all the tiny, funny details in the illustrations—like the underwear on the curtains. It made us want to look closely at every page because there was always something new to notice.
We also loved the word choice in the story. Words like menace and maniac made it even funnier and helped bring the character to life. The running joke about how he couldn’t take the underwear off because he would be butt-naked made us laugh every single time.
The way the author used ALL CAPITAL LETTERS added so much energy and excitement to the story, and the different sections and layouts on each page made it really fun to read.
Overall, we couldn’t stop laughing, and this book is one we would read again and again. If you like silly, creative, and slightly mischievous stories, this is a must-read!

Are you looking for something fun to read to or with your child? This is an awesome book. Take one young birthday boy, a gift from his uncle and get ready for a fun read.
The main character is a young boy who has just received the strangest pair of underwear from his uncle. They are made of wool. Not only are they made of wool, they come with a warning about not wearing them on a full moon. Of course he puts them on. After turning into an underwearwolf he goes on an adventure into the night. This was such a strange and original idea that I laughed and laughed. Along with such an awesome story, you have wonderful pictures from Charles Santoso. The repetition of the phrase "I should have taken them off, but then I would have been butt naked..." cracked me up. I have great-grandson who would love this fun book. We definitely need more books like this. Reading needs to become fun again and it needs to begin with the youngest readers. I can say I highly recommend this book to parents and grandparents, or people like me who love books for all ages.

I received a free eARC from NetGalley in exchange for an honest review. This would be an EXCELLENT choice for an elementary school field trip! It's probably a little over the heads of our toddler/preK crew, but I think 7 year olds would find it utterly hilarious. It's about a pair of underwear that turn the main character into...a werewolf. He spends the night wreaking all kinds of havoc, and frequently thinks to himself that he ought to take them off. But then he would be butt naked! I can already hear the giggles.
(it's also a good companion to Creepy Pair of Underwear, obviously!)

"The Underwearwolf" is hilarious and features a wonderful story and talented artist. A good read for kids and anyone with a sense of humor. The title drew me in, but the art kept me excited to keep turning pages to see more. The concept is fun and simple: don't wear the underpants on a full moon or you'll turn into a werewolf! Of course the drawers are worn on a full moon, and shenanigans ensue. Delightful!
Thanks SimonKids for the ARC! :)

Who doesn't love a good story featuring UNDERWEAR? This book will make you laugh out loud, and it will be the perfect gift for that kid in your life who starts giggling at the sound of certain words... like underwear! A laugh-out-loud book, perfect for Halloween but also a book that can be enjoyed all year round.

What’s not to love about this book? Werewolves and underwear collide in this charming, clever picture book. My kids thought it was hysterical and just the right amount of spooky.
Thanks to NetGalley and the publisher for the ARC!

This is so completely and perfectly hilarious. Who would have thought of combining underwear and werewolves? Comic genius! This is real adventure.
