Who/What is the "Mystic" pokemon at the Tanoby Chambers?
Okay so after completing the stone puzzle on Island 7 (I believe) you hear a loud crash... Etc (obviously the unknown are available for hunting) but whats up with the hint/reference made by the hiker on the last island all the way to the right? The Island is larger than the others and when you first try to walk in the Hiker interrupts you for battle and mentions a mystic Pokemon inside... But when you go after beating the hiker, there's nothing but the typical unknown. What's the deal? Also: found a claim implying that you CAN find a Groudon in FireRed on Island 7 after completing puzzle, is this accurate or more misleading info?
