Piff in a Puffle
Piff strives to find the perfect part for her. If only she could stop puffling and win the approval of Madame Katisha, the ringmaster. But just as she is about to give up, she discovers it's her puffle that makes the other fish laugh.
This enables Piff to embrace her uniqueness. She’s found a place where she belongs. Piff’s puffle is when she expands to double her size (as pufferfish do). In this story the puffle is a physical representation of how a child might experience emotional dysregulation.
