The hit book about a willful young frog with a serious identity crisis and his heard-it-all-before father. Perfect for fans of Mo Willems’s Don’t Let the Pigeon Drive the Bus! and Jon Klassen’s I Want My Hat Back!

Frog wants to be anything but a slimy, wet frog. A cat, perhaps. Or a rabbit. An owl? But when a hungry wolf arrives—a wolf who HATES eating frogs—our hero decides that being himself isn’t so bad after all. In this very silly story with a sly message, told in hilarious dialogue between a feisty young frog and his heard-it-all-before father, young readers will identify with little Frog’s desire to be something different, while laughing along at his stubborn yet endearing schemes to prove himself right.

And look for the hilarious sequels—I Don't Want to Be Big, There's Nothing to Do!, and I Don't Want to Go to Sleep.

It’s Mr. Tortoise’s birthday, and he can’t wait to eat cake with his friends. But there’s a hitch! Mr. Tortoise can’t remember how old he is, so his friends don’t know how many candles to put on the cake. And they won’t stop (or slice) until they figure out the mystery.

Could Mr. Tortoise be as many years old as there are sections on his shell? He’s twice as big as the smaller tortoise . . . so is he twice as old? After the partygoers work through a variety of possibilities, they find their way to the answer with a simple bit of addition.

With text from I Don’t Want to Be a Frog author Dev Petty and hilarious graphic novel–style illustrations from Ruth Chan, How Old Is Mr. Tortoise? will have readers guessing the answer from beginning to end.
