How do you find the under water cave to unlock the reggies?
first you must have a waillord (the last in your team and a relicanth (the first pokemon in your team) dive at route 134 move foward under water and you should find some weird writing on a rock the dive up you should be in a cave go to the end and at the end the back wall should have a row of the writing go to the center and use dig dig should of made a tunnle do again and it should rumble and say it looks like thes another opening somewhere else then go to route 120 and then if you look on your pokenava it should say Ancient tomb now i havent got passed that so good luck i hope you will find them BYE
