Sherman Swaps Shells

It's time to go swapping, Sherman's mom tells him. But finding the right shell isn't easy. Sherman wants one that's spiky and cool, and Mom is looking for a sensible shell for her young hermit crab...A delightfully funny story that introduces shapes, size, and camouflage with a subtle environmental message, the book includes a find-the-crab activity and information about the author and illustrator.
