Creepy Pair of Underwear by Aaron Reynolds illustrated by Peter Brown

While I was looking online for book ideas, my eight year old peered over my shoulder and saw this book advertised and asked me to request it.
Both my boys liked reading this book to themselves.
Jasper Rabbit shops with his mom to purchase underwear.  At the last minute he convinces his mom to buy him a scary pair of underwear.  At night he becomes scared of the underwear and tries to dispose of it.  Much to his dismay it keeps reappearing!
