Cerulean City

Walkthrough
Once through Mt. Moon, you will come out on the eastern side of Route 4. Before long, you will soon find yourself in Cerulean City, home of the next Pokemon Gym. Since the Gym is ready to battle right as you arrive in Cerulean City, heal your Pokemon at the Pokemon Center and then head immediately there. After defeating the Cerulean City Gym and meeting Bill north of Cerulean City on Route 25, you will have to return to Cerulean City to defeat another member of Team Rocket causing trouble.
