Also, with Potter turning everything he touches into gold, what are the possibilities that we could see the Black Lake appear? From
its Harry Potter wikia page:
"It is home to a Giant Squid, Grindylows, and a colony of Merpeople. The lake was also used as the site of the Second Task of the Triwizard Tournament. The Slytherin common room is beneath the lake, accessed through an entrance in the school dungeons. The Chamber of Secrets is also thought to be beneath the lake. At some point, Neville Longbottom's pet toad, Trevor, escaped into the lake, joining other toads that lived there."
What do you guys think?
