Morning Visit
Go to the statues outside of the Sunset House any time during the day. Each statue will be standing in a certain pose. Draw a diagram of the statues or make notes of their poses so that you can easily remember how they are positioned.
Nighttime Visit
When you return to the Sunset House at night, you will notice that all of the statues are all standing in different poses. The diagram you drew earlier is the clue you need to open up the Sunset House.
Interact with the Statues
If you approach the statues at night, an action button will appear on your screen so that you can interact with them. Pressing the button once will change how the statue is positioned. You can reposition the statues any number of times.
Position the Statues
With your diagram in hand, you will be able to match the statues up to their original positions. Interact with each statue as many times as necessary to revert it to its original position. Once all four statues are locked in place, the Sunset House will take a more solid form and allow you to enter.
