"Annable's soft, expressive illustrations juxtapose Ernesto's easy, optimistic joy with Peter's apprehensive courage as they explore the world for the first time. Many readers will look forward to the next adventure. A solid pick for readers who have graduated from Elephant and Piggie, Frog and Toad, and Narwhal and Jelly"–Kirkus

"This is a funny, touching tale... The characters’ different notions of adventure and bravery recall other odd couple friendships, such as Mo Willems’s Elephant and Piggie and Holly Hobbie’s Toot and Puddle."–School Library Journal starred

"Annable’s gift for caricature and zippy dialogue shines through, as he celebrates his characters’ contrasting temperaments without a hint of snark."–Publishers Weekly

"Annable skillfully communicates a message that will be especially welcome to anxious kids—that sometimes small adventures take even more courage than big ones. Readers will be eager to reunite with Peter and Ernesto in the next installment of this new graphic novel series."–The Bulletin of the Center for Children's Books
