surf around the massive island that is sootopolis city, then use dive at a deep place. there should be a cavern underwater. go in it, then you should have found the submarine. if you use dive there you can get to sootopolis :-)
You need to find the submarine that team magma stole.
You can find Maxie's Submarine in Seafloor Cavern on Route 128. From Mossdeep City, surf, and then use dive. Go all the way down till you get to the circle. go around it, an enter the underwater cavern. There, you will find the Submarine.
Find the submarine Team Magma stole and defeat themand awaken Groudon
In Emerald you surf SW of Mossdeep. You use dive and go in a cave thing underwater. It is there. It might be somewhere like it in Ruby. Note: I *may* have mistaken it since I haven't been playing for a while.
its on rote 128 i have not found it and i am stuck there so i am lookin for it all day
You go to their secret base just tright of lilycove
After you find the submarine you use dive up to the surface.
you cant find him in Pokemon ruby instead you find may.
Pokemon ruby's version IS Pokemon ruby.
You can't in ruby.
That depends, if you have yet to find the Team Magma Submarine under water you must go do that, if you have already done that, go to the north point on the left side of Sotopolis and enter the cave there.
is ruby bridges doing find in 2017
