so, you made Regirock faint? is that the one you're talking about? here, i'll tell you how to open the caves. for Regice (Route 105), you run around the room on the edge of the wall, without going away from it, once. for Registeel (Route 120), you go to the middle of the room and use Flash. for Regirock (Route 111), you go to the middle of the braille, go left left down down, and then you use rock smash. hope i helped
^what she said + take 50 ultra balls at least, just incase
