A dangerous but gentle bird
The fwooper is one of the many animals that can be seen in Newt Scamander’s famous magic suitcase in the Fantastic Beasts movies, especially in The Crimes of Grindelwald. Indeed, Newt Scamander is an English wizard passionate about fantastic creatures who has started to write a guidebook listing all of them. So he walks around with his suitcase, which looks like an ordinary suitcase for muggles, when for wizards he can open it and go inside, which houses a whole world of creatures that Newt has collected to have as much space as they need until they can be released into their natural habitat. The fwooper is a bird of African origin whose cry can drive you crazy, which forces Newt to place a permanent silence charm when he has to take care of him.
