I believe it's in a cave on 7th island.
Ruby/Sapphire/Leaf Green/Fire Red/and i think Emerald. if not, trade from emerald to Ruby/Sapphire, and from ruby/sapphire to leaf green. You need to have the Sapphire and Ruby before you trade. you get these after the elite four.
The ruby and sapphire are on fire red and leaf green don't worry about the in ruby sapphire or emerald.
behind the door is leaf green u enter the Pokemon leaf green world
Yes
You can but you have to trade it over from Leaf Green.
You'll need to trade a Rayquaza from Ruby, Sapphire, or Emerald if you want to have a Rayquaza on Leaf Green.
You simply can't, coz Sapphire and leaf green are totally different games. I have them both, i got the Sapphire first, and when i got leaf green lots of things were'NT there because leaf green was made before Sapphire and they probably added new stuff to the latest games. Except if you ment the berries, you can find them in the trash cans sometimes. Z
FUSCHIA CITY IS IN FIRE RED & LEAF GREEN NOT SAPPHIRE..VERONICA
You can not get a Growlithe in Sapphire. You'll need to trade with Fire Red or Leaf Green.
Trade from emerald/fire red/leaf green.
The six island in some ruins.
its not on treasure beach
