How do you solve the three crystal puzzle in Pokemon Mystery Dungeon Explorers of Darkness?

Answer 1

The three crystals puzzle you encounter in Pokemon Mystery Dungeon: Explorers of Darkness is really quite simple to complete. It requires you to have all the crystals matching in colour - which resebles the colour of 'Azelf's spirit'. This is achieved by touching each crystal (by pressing the 'a' button once you are close to it) until it turns the right colour. Your partner Pokemon gives you a hint before you figgure out the puzzle. Your partner wonders alloud about the colour of 'Azelf's spirit' and comes to the conclusion that it is the same as running water or a lake (blue), which also matches the colour of Azelf itself. So, you must turn each crystal blue in order to open the entrance to Azelf's lake.
