Violently pink and purple Pygmy Puffs were bred by Fred and George Wealsey, and ended up being a Hogwarts Hit. We’re pretty sure they went through the Ministry of Magic to get the appropriate breeding license. Bred as miniature versions of Puffskeins, Pygmy Puffs became something of a craze in the wizarding world. And for heaven's sake, hamsters and guinea pigs ain’t got nothing on these little balls of fun.
