I basically have 2 questions. Where are the 4 puzzles for the unknown pokemon. I have completed 3 so far, but can not find the last one. I was guessing that it was in the dark cave, but I no longer have rock smash to get through. I have been through the puzzles at the 2 caves by ruins of alph and the one you have to go through union cave to get to. So my Q's are:
1. How do I get to the last puzzle?
2. Can I get rock smash again after I lose it and if so where?
