Well, it's been a long time, and we're still renovating this pit. And I mean pit. Did you know that the Fellyfire Asps originated here? Yes, right here in Diagon Alley. Many say it's fairy tale, myth, but I assure you it's real. See!! Look here at this speck on the wall. It very well could be a fragment of the remains of a Fellyfire Asp.
Uh, Mr. Lovegood, can I clean the Ghoul excrement?
Ok, well, apparently it's not Asps remains. But I know their existence is more than myth.
