Pokémon Gold and Silver/Mahogany Town

By now the egg should have hatched, if it has click here

When you first come here, you can't do much here, the house with the sign next to it is the mart but sells useless items and a few potions and PokéBalls. To get to the gym go north to the Lake of Rage but first, fly to somewhere to get some Great Balls, you have a battle with a very very rare Pokémon (A Red Gyarados).
