"After Alfred the turtle spends a morning at the park, his foot is bumpy and sticky, and it hurts too! It's up to Pipsie to figure out what gave him a tender tootsie."--dust jacket.

"Pipsie and her turtle best friend, Alfred, are on the best school trip ever--a nature scavenger hunt! The team who finds Seven Wonders of Nature first wins. But that isn't all Pipsie and Alfred have to find. Someone has stolen the PB&J!"--Dust jacket.

Let's make this mystery history. Pipsie loves everything wild--from dragonflies to oceans to tall, tall trees. She also loves solving mysteries. That's why 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 treehouse headquarters, and begins to search for clues.
