Pipsie loves everything wild-from dragonflies to oceans to tall, tall trees. She also loves solving mysteries. That's why she's a nature detective! When she and her turtle, Alfred, notice that their new friend, Frannie the caterpillar, has vanished, Pipsie is on the case. She grabs her magnifying glass, goes to her tree-house headquarters, and begins to search for clues. It's time to make this mystery history! Bursting with personality, this engaging story introduces a spunky new girl detective, a scooter-driving turtle who loves to eat, and a string of simple scientific clues that will keep kids turning the pages until the mystery is solved. Two pages of nature fun facts at the end of the story offer even more information for young nature detectives.

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.
