*Nadia sizes the oppotunity and raise hand* I have always been curious, professor, about Red Caps, to know if we are studing them. They don’t figure as a magic creature in Newts Scamander’s book, nor do I think they would be considered inside the ‘Beings Division’, nor boggarts nor dementors are, and that’s exactly the *things* to fight against in DADA coincidentally. Are they spirits, or apparitions maybe? And what about the Lethifold, because it *is* a fantastic best, yet a simple Patronus Charm can push it away, as if being weightless.

Grindylows, Kappas, Kelpie, Lethifold are *demons* but ARE considered beast though...
