The Wolf in Underpants

The Wolf in Underpants (Le Loup en slip) is a French children's book written by Wilfrid Lupano with drawings by Mayana Itoïz and Paul Cauuet, published in 2016 by Dargaud. Nathan Sacks translated the book into English, and that version was published by Graphic Universe in 2019.

The book is about a village of animals who wrongly believe that a wolf is set to attack them, but the wolf turns out to be innocent and the others realize their fears were false.

Publishers Weekly described it as a parody of The Big Bad Wolf. Henrietta Verma of Credo Reference stated that the illustration work resembled that of Richard Scarry, and that the storyline refers to "fake news".

In France the book is found in comics sections and children's sections of bookstores.

Creation and conception
It is a spin-off of The Old Geezers, which featured "The Theater of the Wolf in Underpants" (Le théâtre du loup en slip). Itoïz had previously made paintings of wolves in underwear in a forest to calm her son, who had a fear of wolves, and the authors of The Old Geezers (Lupano and Cauuet) had inserted the character. Itoïz later proposed having a children's book series about the wolf.

Reception
Verma stated that overall the book is "A winner" with a "fast-moving, amusing narrative", though she stated the end portion is "pedantic".

Kirkus Reviews praised the book for having "a timely, smart message".

Publishers Weekly praised the English version for being "sly" and that the images are "gems of comic timing and choreography".

Deborah Stevenson, a reviewer of the Bulletin of the Center for Children's Books, stated that the work was "humorous" and held interest of children who did not know of the political dimension behind the work.

In 2020 it was nominated to receive an Eisner Award.
