This is our way of solving the final puzzle of P.T.
The key step is to hear the second baby giggle. You might find lots and lots of guides online, but almost none of them agree on the exact way of triggering that (the first and the third giggle are easy, though).
I suspect that there might be some redundant steps in our play. But at least this method works for us and we just want to share it on Youtube. If you found another simpler solution, or you want to report that our solution doesn't work for you, please don't hesitate to leave a comment below. Discussions welcomed.
