Mt. Moon

Mt. Moon is a mountain located in northern Kanto, between Pewter City in the west and Cerulean City in the east. The three locations are connected through Route 4.

Mt. Moon is known for being one of the few places where wild Clefairy can be found and for its frequent meteor falls. The shards of meteorites that fall here become Moon Stones, which explains the mountain's name. The mountain is also known for being home to Pokémon Fossils. Brock digs for Fossils here in his spare time.

Mt. Moon's interior is a large cave spanning three floors. Being the first cave that the player will come across with, Mt. Moon has a very long and complex structure.

The first floor contains several ordinary Trainers, while the basement floor contains members of Team Rocket who are trying to steal Fossils from Mt. Moon to market them for money. On the player's way out to Cerulean City, the player will find two Fossils, the Dome Fossil and the Helix Fossil that a Super Nerd claims to have found first. After being defeated in battle, the Super Nerd lets the player choose one of the Fossils while he will take the other one.
