Best-selling author/illustrator duo Robert Munsch and Michael Martchenko create a wacky classroom story as Christopher offers some of his mysteriously "delicious" cookies to his parents and teacher!

Christopher's playdough cookies may look delicious, but when he tricks his parents and teacher into eating them, they soon realize that these "cookies" are NOT what they seem! When they decide to give Christopher a taste of his own medicine, and he falls for his very own trick, the entire class is in for an hysterical adventure!

With a playdough recipe included, here is yet another off-beat story from the author of bestseller LOVE YOU FOREVER, bound to have kids and cookie fans of all ages cheering for more.
