The Harry Potter series is home to a bevvy of magical creatures, so much so that there was a spinoff book and subsequent movie series written all about them. But even the main Harry Potter series itself is no stranger to the fantastical, including the strange magical animals and creatures that make appearances throughout the story. Sometimes these magical being are of great importance to the story and have a lot of impact, while others are simply table dressing, helping make the Wizarding World feel a little more fleshed out with the details of their existence.
