Edna & Harvey: Harvey's New Eyes

Chapter 1

Make sure you make a manual save prior to unlocking this trophy so you can reload it and work towards the game-spanning loathing mini games.

After helping the old man (mnemonic device), he will give you an old book. Bring both the book and the air hammer to Frank. Once he has both, you can use the old book with the stones on the ground to start a simple puzzle: just make sure no row or column has a duplicate symbol. After you've done that, you'll need to match three scraps to the symbols you've placed – these scraps will always cover the third and fourth rows of the book. When you've done both, this trophy will unlock.
