Though the story is told through very little text, the mathematics inherent to each exchange extends to older readers. If they trade four of their six oars, how many should be left? These questions are not explicitly asked, but the illustrations always bear out the answers. The result is a delightful adventure with a sweet underlying message, and the treasure maps that grace the end papers are a perfect final touch.
--Booklist (starred review)

As he did in Have You Seen My Dragon? (2014) and Have You Seen My Monster? (2015, both Candlewick), Light brings his exceptional talent and clever storytelling to young pirate lovers and fans of all things nautical...Several pages of sequential panels assist the minimal text in telling this engaging story of ingenuity and resilience. A fun-filled swapfest for salty dogs and landlubbers alike.
--School Library Journal (starred review)

The boy's wooden leg is a physical difference that isn't remarked upon and doesn't hinder him from doing what he likes, and the fact that it's the boy who comes up with the plan is satisfying, too. Light's story will leave readers with much to think about.
--Publishers Weekly

The limited, repetitive text will be a boon to beginning readers, and the unusual deployment of limited swaths of matte color to accent the sea, the protagonists, and their trades will invite older viewers to consider how color guides the eye across a spread.
--Bulletin of the Center for Children's Books

Faintly reminiscent in its cheerful preposterousness to Bob Gill's "A Balloon for a Blunderbuss" (1961), Mr. Light's tale features airy pen-and-ink illustrations that are brightly pigmented in only a few places--so readers ages 4-8 may want to keep the book away from their younger siblings, lest they be tempted to color in it.
