[Halloween] Olivia: 'Find My Daddy'

I know I might be asking for a lot, but could you please go back inside and help escort my daddy out? He's stuck inside the Piano Room, and I believe one of the ghosts holds the key for entrance. Could you get me this key?

I knew you'd do it! Hee hee. The only thing is, there are a bunch of keys around the house and I'm sure you'd have trouble finding the right one. So, could you look for 25 Silver Keys, 25 Gold Keys, and 25 Brass Keys, then bring them back to me? I'll be able to look through them all and identify the correct key. And please hurry!

How can you tell me to 'suck it up' and go inside when you're afraid to go in yourself?

Please save my father who is confined in the Piano Room by finding the right set of keys. Were you able to find them yet?

Oh, that's great! Now, let's see which one has just the right cut...

I was never too good at math, but I sure can count and it looks like you don't have enough yet. Please come back when you retrieve 25 Silver Keys, 25 Gold Keys, and 25 Brass Keys.
