Hello,
Can someone tell me how to get past the purple ghost in the room with the piano. I keep shooting it but it just keeps coming back, thanks for any help.

You just have to keep shooting it,it will eventually die. You might die once or twice though too lol just keep using reducto and you'll win. Just keep in mind that level is long lol

The Shrieking Shack

After you defeat the Womping Willow, you have to get the ingredients to a potion, once inside the tree. I was only able to find one.. And I can't jump anywhere else but to the beggining of the level. Help anyone?
