When you enter the room, there will be a Creeper at the northwest corner of the room behind a toppled sofa, so take care of that first before using your Black-light to restore the organ.

Play the organ to make the Polterpup appear, and it will run behind the organ. Go and follow it, but the Polterpup will escape to the room to your left. If you try to leave, the doors will be blocked and a Gobber and three Greenies will appear. Go to the West Bathroom once you're done.

Crow's Nest, West Hall, and West Bathroom

From the Conservatory, head west into the Crow's Nest and keep going until you get to the West Hall. Enter the West Bathroom at the north and the Polterpup will hide immediately when you arrive.
