I'm currently trying to open the passage to the 4th Unown letter Puzzle. The clue it gives me is "WATER" spelled out using the Unown. Which item are you supposed to use to open this passage way? Also the UNOWN ! And ? Still haven't shown up, and I've already caught all 26 letters of the Unown. I was told they can be found inside the hall entrance, but there's nothing there, even after using "Sweet Scent" nothing appears at the hall entrance. Any Advice on how to obtain Unown ! And ? Forms?
