While escaping the Dungeon, you’ll eventually find a button that unlocks spikes in front of a cell. In that cell there is the key.

You will collect this key during the story.
After overcoming your fear of drowning, the key will be inside of the wormhole that Mari leaves when she disappears into the window/curtain.

N – Near a game of roulette.
This one is simple. Once you enter the casino for the first time, it’s on the left side of the room next to the machines.
O – Amongst other O’s.
Outside of the casino on the right side, there is a haunted pool. Enter the pool to be transported to the ghost party.
You can pick up the ghost quest here too, which you have probably seen things for around the world already.

After re-acquiring Aubrey, go to the 4th floor and enter the room on the right. Continue forward by going behind the mustached ghost. From here, go up as far as you can, using Aubrey’s ability as you go up higher and higher. Eventually, you will climb a ladder to acquire the key.
Location – Highway
