Fantastic Beasts And Where To Find Them - The Missing Beast
In the 3rd Harry Potter book, the Hinkpunk is mentioned in one of Harry's classes (Care of Magical Creatures, I think.) It's nowhere to be found in Fantastic Beasts, and the Hinkypunk was made up before Fantastic Beasts was written.
Well, this may not be the most recent edition of the book, after all, it's only the 53, maybe in, say, the 57, it mentions Hinkypunkns and also Bogarts.
