You will get it in Ecruteak city, first enter the Ecruteak Dance Theater, you'll find a rocket grunt. Second, battle him. He has a Level 12 male Koffing. Ha! Easy to do with your starter, and when you win the man with the Psyduck will give you The HM03 Surf. Hope I helped. Same goes for Soul Silver. (SS)
Also, what is your friend code?
