The Playhouse Key can spawn:
- Inside the Melon
- Inside the Special Room Locker
- Inside the Screwdriver Safe
- In the left drawer of the Study
- On the Garage table
- This key is not required to beat the game in the first item location, because the Weapon Key is in the Cogwheel Safe in the Playhouse, and the Crossbow is optional. It is also not required in the fifth item location as the Spark Plug is in the Cogwheel Safe, but this is only true if the Player wishes to escape by Main Door. It is also not required on Tool Presets 3 and 4 if the Player wishes to escape by the Car, as the Master Key is in the Cogwheel Safe. However, it is required on Tool Preset 2 on both ways of escaping, as the Padlock Key is in the Cogwheel Safe.
