Stories kids read. Ideas kids wear.

This is the complete Leaf Sheep experience in one ready-to-gift box: a hardcover book by New York Times best-selling author Susan Verde, the matching Peek-and-Discover tee, and a hands-on science surprise, all packed in a premium keepsake box with a magnetic latch. No wrapping paper required.

The story. The leaf sheep is a sea slug barely a quarter inch long, so new to science it was only discovered off the coast of Kuroshima, Japan in 1993. It steals chloroplasts from the algae it eats and uses them to make energy from sunlight, like a plant. Scientists call that kleptoplasty. Kids call it the best word they've ever said out loud. Susan Verde turns this tiny animal into a page-turner filled with real photography, prediction prompts, and vocabulary like "cerata" and "rhinophores."

The tee. Butter-soft, tagless, made from organic cotton and recycled polyester. A peek-and-discover flap hides a leaf sheep underneath. Kids lift it, show it off, and get to explain the animal that eats sunlight to everyone who asks "what is that?"

The first discovery happens before the book is even opened: a small bag that dissolves completely in water, revealing a collectible hangtag for their backpack. Yes, that is real science too. The book explains how it works.

Ages 4 to 10. Sizes 3-4Y to 9-10Y. Free shipping on all orders. 5% of your order supports Ocean Blue Project, a nonprofit dedicated to marine conservation.

About The Book

An interactive children's book, written by New York Times best-selling author Susan Verde

We know what life can look like on land, but under the sea is a whole new world, filled with all kinds of creatures. Have you ever heard of a Leaf Sheep? One of the cutest and most unusual animals on the planet, the Leaf Sheep is small, but complex. What is so amazing about these little sea slugs?

As children turn the pages of this book, they will encounter striking photographs of the leafy green sea creature known as the Leaf Sheep. They will discover why it carries this unusual name, what scientists call it, and whether it is truly related to sheep or has more in common with plants and trees. Readers will learn where the Leaf Sheep lives, what it eats, and how it performs photosynthesis—creating and storing energy that it turns into food.

It is written and designed to reflect the Leaf Sheep off the Sea collection and appeal to and engage a wide variety of developmental stages, giving families a reason to move away from a screen, to sit together, and find joy in reading.
