I already know about Metal Coat and TM 42 but I'm talking about the sentence that Psypoke gave us in the walktrough for Island 5 when talking about the Memorial Pillar: " At the southern end of the island, choose surf and head alle the way east and south as far as you can. You'll end up on a small island with a statue made of rocks called "Tectonix". Examine it, and choose to leave a Lemonade there. The guy next to you will give tou TM42 - FAcade as a token of appreciation. (YOU REALLY HAVE TO DO IT YOURSELF TO FIND OUT THE STORY BEHIND THIS ...). Immediately to the west and south is a Metal Coat.
I only wanna know what is the story behind this coz I searched for any possible clue and, unfortunately I didn't find any.
If you have the answer... please... answer !!
