How do you get raimbow ticket in Pokemon FireRed?

Answer 1

First, you have to had beaten the elite four. Second, talk to celio and he will give you instructions to go to mt. ember on island one. Third, You will see either one or two (i can't remember exactly) team rocket/s on your right just when you enter the mountain. There covering a entrance to go further inside the mountain. Defeat them and go into the entrance. You will go through a series of boulder mazes where you have to move with strength. When you come to two roads, (one on the right and one on the left) take the left one and you will go down a ladder(as always lol) were you will see a place with somewhat strange stones. Go down the ladder to your right and there is the ember stone which you need to get the rainbow pass from celio.

Tip: i would recommend a escape rope or a POKEMON that is able to use dig because once you get the ember stone, you have to go the same why you came in mt. ember.
