For this Puzzle, we must guide our partner over a hallway filled with tiles. If they step on the wrong Tile, they will die.

Ask the explorer what symbols they see on their book. You will have to find the book that matches the symbols they describe. Once you find the book, you need to flip it over and read them the directions.

They will use these directions to get across the puzzle without dying. Once they cross the puzzle without dying, your Cheevo will pop🏆
**If for some reason you fail. No worries. You can pick this puzzle in the Chapter Select before you start the game. So you DO NOT need to play all of the previous puzzles again to try for this Perfect Puzzle.
