From the creator of While You're Asleep comes a hilarious pourquoi story about a burrowing tortoise and her mouse best friend-as well as mishaps, misunderstandings, and the friendships you make along the way.

Tortoise and Mouse are more than just friends and burrowmates. They are best friends and best burrowmates. When their home gets flooded, however, it's up to Tortoise to dig them a new place to live. And so she digs a room of her own and a room for Mouse. But where is Mouse?

Noticing the fresh burrow, Bunny asks Tortoise if she could dig a room for her as well. Then the Spotted Skunk. The Mole Skinks. And the Wolf Spider, the Frog, and those moths...So Tortoise digs. Seemingly everyone else wants to be her burrowmate except for Mouse-where did she go?
