on deep water and heres a hint:suicune is bewtween deep water somewere in the johto region
You'll need to teach the Pokemon Surf and go to the water and press A. (If not go in party and select the Pokemon that knows Surf)
u will have to cacth a Pokemon that can learn surf that's the only way
you can't...
Its becouse your ds is old
Pokemon shiny gold can be only be played on the computer
i think if you have a gameboy Pokemon game you might be able to transfer it to your ds{ the slot for gameboy games is at the bottom of your ds}
its Pokemon heart gold and you surf east of newbark town
Surf around Lake of Rage
learn surf
You have to get a pokemon that can learn the hm surf and u go up to water and press A, then it will say surf, press A and swim! to get off just go to land or fly.
cuz they think Pokemon silver and gold are better than Pokemon crystal.
when you get HM surf just get in the water and there's only water pokemon.
