The six island in some ruins.
I believe it's in a cave on 7th island.
you don't you get it from bill
======================================================================================================================================== you can not go there it is only for fire red and leaf green
you go to the 7 is island
fix the machine on island 1 find the ruby and the sapphire stones
Birth Island is not available on Pokémon Ruby or Sapphire. You can only go there in Fire Red, Leaf Green, and Emerald.
you can't get him on emerald ruby or Sapphire. you have to trade him from Pokemon leaf green or fire red to emerald. on Pokemon fire red and leaf green you get him at the end of island 1.
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.
Yes
You can but you have to trade it over from Leaf Green.
