In Nancy Drew: Shadow at the Water’s Edge, you can find up to 4 Easter eggs for fun. If you find at least one, you will get the meta award at the end of the game.
Egg 1: From the Pachinko Parlor prizes
Egg 2: Garden Lantern
Egg 3: Purikura Booth
Egg 4: Puzzle Box on the desk
To get Egg 1: If you place 15-30 balls in the prize drawer at the Pachinko parlor, one of the prizes will turn into an Egg for you to get.
To get Egg 2: Use the recorder at the stone lantern in the garden to record the hot spot. Play that track on the player in the shed for the clue. Follow the clue to the main baths and look under the floor tile that is a different color than the rest.
To get Egg 3: Watch the DVD in Yumi’s apartment. After a few minutes in real-world tjme, you will get a text picture of a white ghost. Print out that picture at the purikura photo booth and you will get the egg.
To get Egg 4: After you solve the puzzle box on Miwako’s desk and opened her password folder, return to the puzzle box and open it again (solving it a second time). The egg will be inside.
BONUS: You can use the Easter eggs! Use an egg on any of Rentaro’s Sudoku, Renograms, or Nonograms sheets for an auto-solve feature. You get one use per egg.
