Mt. Moon (Japanese: お月見山Mt. Otsukimi) is a mountain located in northern Kanto, between Pewter City in the west and Cerulean City in the east. It also provides access to Mt. Moon Square in Generations II and IV. Climbing does not seem to be possible; to get past it, travelers always need to travel through the caves.
Mt. Moon is known for being one of the few places where wildClefairy can be found and for its frequent meteor falls. The shards of meteorites that fall here become Moon Stones, which is why its name is Mt. Moon. The mountain is also known for being home to Pokémon Fossils. Brock digs for Fossils here in his spare time.
In the Generation I games, 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. In Pokémon Yellow, after the player obtains one of the Fossils, Jessie and James will appear for the first time and battle the player. However, they are not referred to as such in-game, sharing their Trainer class with that of ordinary Team Rocket Grunts.
When entering through the Pewter City entrance, there are two possible paths: one in the eastern direction and another one in the southern direction. By traveling south and then east, the Cerulean City entrance can be found. However, by traveling east from the Pewter City entrance, the player will end up at the northern side of Mt. Moon, where Mt. Moon Square, its summit, is located. By traveling south in Mt. Moon Square, and entering the southern cavern, there will be a ledge which can be jumped to instantly access the Cerulean City entrance.
Mt. Moon Square is an area in the heights of Mt. Moon. On Mondaynights, two Clefairy will dance and pray to a large Moon Stone in the square. By interrupting the dance and breaking the stone using Rock Smash, Trainers can always find a Moon Stone below the rock. There is also a small shop here that sells a variety of goods.
Mt. Moon's incarnation in Pokémon FireRed and LeafGreen is very similar to the original from the Generation I games. The only major change done for the remakes is the items found within the cave. Another addition is a man who is excavating for Fossils in the north-eastern corner of the first floor. He is a friend of Brock and is a source of one of Brock's Fame Checker entries.
Mt. Moon's incarnation in Pokémon HeartGold and SoulSilver is essentially intact from the Generation II games, but with updated graphics enhancing the scenery and depicting its mountainous nature more accurately. The only significant changes are in Mt. Moon Square, where four Clefairy will appear instead of the only two that appear in the Generation II games, and the background music being changed to つながりのどうくつ Union Cave, a Johto theme, from イワヤマトンネル Rock Tunnel, a Kanto theme, which is the background music that plays here in the Generation II games (the latter being itself a remix of おつきみ山のどうくつ Mt. Moon's Cave from the Generation I games).
Mt. Moon is also where Red battles Bruno in the beginning of this chapter.
In The Electric Tale of Pikachu manga
Mt. Moon appears in the third chapter of The Electric Tale of Pikachu, Clefairy Tale, where Ash tries to catch a Clefairy in the Mt. Moon area. After three agonizing weeks in the wilderness, Ash and Pikachu accidentally follow a Clefairy into an occupied Onix nest. Ash and Pikachu are driven into the maze of tunnels the Onix has created. After rejecting using Fearow, Beedrill, or Pikachu, Ash decides to use his Butterfree. Butterfree uses Psychic, which weakens Onix, but also confuses it — causing it to thrash around and cause a cave-in that buries Pikachu and Ash under a pile of rocks. After escaping, he meets Professor Oak and Bill, who have been studying a group of Clefairy living in the Mt. Moon area.
