HM 03 Surf - Get this from Wally's Uncle after you beat your father in the 5th gym
Events
This is where you meet Wally for the first time in your father's gym, which you need to do before you move on. If you try passing through town instead, a citizen will stop you and direct you to the gym. When you meet Wally in the gym, you will be shown the procedure to capture Pokémon.
This is also where you fight your father in the 5th gym, but only after you get the first 4 badges.
