What happened to Alfred's foot? After a morning at the park, Alfred the turtle's foot is bumpy and sticky, and it hurts, too! It's up to Pipsie to figure out what gave him a tender tootsie. As Alfred shows Pipsie where he went that day, they come upon all kinds of insects--from ants to spiders to honeybees. And the clues Pipsie uncovers lead her on a twisty, turny, and even slightly stinky nature mystery.
