From Caitlin Rose Boyle (Jonesy, Frankie and the Creepy Cute Critters, and Frankie and the Beastly Bog Song) comes the next Frankie Fairy adventure perfect for young explorers! Frankie Fairy loves to learn about creepy critters! Joined by her biologist mom and equipped with a field guide full of creepy critter facts, Frankie finds all aspects of nature fascinating! That is until Tuna, her beloved pet wooly bear caterpillar, is nowhere to be found. Frankie’s mom thinks Tuna must finally be entering metamorphosis—a time of change when Tuna would transform from a cuddly caterpillar to a flying moth. Frankie wants Tuna to stay the same little fuzzy worm she’s always been. But when she discovers the beauty of the transforming world around her, will she accept that one day, everybody—even Tuna—experiences some kind of change?
