Creepy Pair of Underwear!

Creepy Pair of Underwear! is a 2017 children's picture book written by Aaron Reynolds and illustrated by Peter Brown. It is a part of the Creepy Tales series of books, which also include Creepy Carrots! and Creepy Crayon!.

The main character, Jasper Rabbit, is interested in a new pair of underwear with Frankenstein patterns but finds it unnerves him and tries to get rid of it.

The book uses pencil work and digital coloring, and uses black and white imagery.
