You can't. You'd have to trade it from a Pokemon FireRed or LeafGreen game to get it in Sapphire.
You can't catch Ditto in Pokemon Sapphire, but you can trade it to your game from Pokemon Emerald/FireRed/LeafGreen
You can't.
no.
Seedot can't be caught in Sapphire. You have to trade it over from a Ruby/Emerald game
if you mean trade them back you can't because they are already on your game unfortunately Hope this helps
No you can't, but you can trade it from a Pokemon Emerald/FireRed/LeafGreen game.
Zangoose does not appear in Pokemon sapphire, but you CAN get it. To get it, you must trade Pokemon with your friend if your friend has Pokemon ruby which is the only game you can get zangoose in. Or you can just buy Pokemon ruby.
You can't get Eevee in Pokemon Emerald/Ruby/Sapphire, you have to trade it from another game.
You can't. You have to trade with an Emerald game that has it, which means that the person owning that game has all 260 Pokemon in their Pokedex.
You can't catch it in Pokemon Sapphire, Ruby, Emerald. The only way to obtain it is to buy it in the Game Corner for 9999 slot coins in Pokemon FireRed and LeafGreen and then trade it to your Ruby/Sapphire/Emerald game.
If you want deoxys in Pokemon sapphire, you need an action replay, or an game shark. Or trade from an emerald game that been to birth island, and has caught deoxys.
