A Pygmy Puff is a fictional creature created by author J.K. Rowling in her "Harry Potter" book series. The creatures first appear in the sixth book, "Harry Potter and the Half-Blood Prince."
Pygmy Puffs are miniature versions of Puffskeins. Puffskeins are soft, spherical, furry creatures that are mustard yellow in color. Pygmy Puffs have a similar appearance, though they are smaller and usually pink or purple. They roll around and make a squeaking noise. The first Pygmy Puff was bred in Fred and George Weasley's magical shop, "Weasley's Wizard Wheezes." Fred and George sell Pygmy Puffs to students to keep as small pets.
