lilycove city or something like that
If by sapphire you mean kyogre (cover star of Pokemon sapphire) beat team aquas base,find them underwater on route 128 go up through the cave and he runs off.go to cave of origin.
You can't
same way u do in sapphire or emerald go to lilycove city and go down to the beach surf out to the left and there is a big rock that is the aqua base
Team aquas base where they first hide the submarine. It's in one of the rooms
Do you mean team aqua's base? or lillycove? coz if it is team aquas base than it is beside lilycove. Go to the beach and run north till you see a guy with 3 Pokemon in the water then surf from him north till you see a cave and that is team aqua's abse. :)
Their base is always at Lilycove, but you can find them other places (Mt. Pyre, Underwater Cavern, etc...).
well you go swim then find the dark spot of the largest sea then face the same pokemon then catch it,the battle team aquas
beat the team aqua base
