How do I catch Rayquaza?
This event can only happen after beating the Elite Four. The Sky Pillar (inside which Rayquaza rests) is located east of Pacifidlog. Surf east of Pacifidlog, keeping to the north. Make sure you have a Mach Bike with you and lots of Ultra Balls and Timer Balls. After a few floors, you’ll start to see cracks in the floor. The Mach Bike is just fast enough to help you zoom across. However, the bike needs one tile to gain “momentum” and you can’t slow down or you’ll fall through. You’ll see what I mean when you get there. Make your way up the tower. On one floor, you’ll have to fall in just the right place to continue. After a few tries, you should have made it up to the top, where Rayquaza roosts. It’s a level 70 and pretty hard to catch. Good luck!
