Kanto Route 4

Route 4 is a short path in northern Kanto that connects Cerulean City to the eastern exit of Mt. Moon. There are two karate guys who are move tutors that will teach you Mega Punch and the other one will teach you Mega Kick. On the western side of Route 4, there will be a man in the Pokémon Center west of the Pokemon healer in Pokemon Red, Blue, Yellow, FireRed, and LeafGreen who will give you a Lv 5 Magikarp for P500 that only knows Splash. Mt. Moon splits the West from the East on Route 4 as a Mountain like Mt. Coronet. This is where you get your choice of getting the Helix Fossil or the Dome Fossil first.
