Carry on with the game until you get hm surf and hm strength then go back to vermillion city. enter the harbour and look at the s.s. anne. Go right and surf across the water. Carry on going right until you see a lorry use strength and push the lorry out of the way. you will find a pokeball. Get it and inside it will be mew.
