Elinor learns how plants survive in a hot and dry climate in this fourth picture book based on the popular TV series.

Ari loves the backyard soup Elinor makes him with vegetables from her garden. So when Elinor visits her grandparents in Desert Town, she decides to make backyard soup for them, too. But when she goes to collect the ingredients, Elinor doesn't find the same vegetables! Why are different vegetables growing in her grandparents' garden? Could it be connected to how it's hotter there, and the dirt is dustier and less squishy than the dirt back home? Elinor wants to find out!
