Pokémon world locations

Mt. Moon (Japanese: オツキミやま or おつきみやま Mt. Otsukimi) is a mountain located in northern Kanto, between Pewter City in the west and Cerulean City in the east. 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 wild Clefairy 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.

Geography

Generation I

In the Generation I games, Mt. Moon is a large cave with many floors and connectors. The interior of the mountain is comprised of caves spanning three separate 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, which are called Rocket (Japanese: ロケットだんいん Team Rocket Member) in this generation.

Players will first encounter wild Clefairy here at Mt. Moon.

Generation II

In Pokémon Gold, Silver, and Crystal, Mt. Moon has dramatically decreased in size from Pokémon Red, Green, Blue, and Yellow. It now has only one base floor with a couple of connectors. It is also a spot where the player's rival is training near the entrance and he will battle the player for the sixth time during the game.

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 Monday nights, 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.

Generation III

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.

Generation IV

Diamond, Pearl, and Platinum

Although it does not appear in Pokémon Diamond, Pearl, and Platinum, a guest at Hotel Grand Lake by Lake Valor mentions Clefairy dancing under the moon at Mt. Moon.

HeartGold and SoulSilver

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 おつきみのどうくつ Mt. Moon's Cave from the Generation I games).

In the side games

In Pokémon Pinball

Pinball Blue Mt. Moon.png

Mt. Moon appears on the Blue Field as Area 1. Catchable Pokémon include Rattata, Ekans, Clefairy, Zubat, Paras, and Geodude.

In the anime

Mt. Moon in the anime

In the main series

Mt. Moon seems bigger in the anime than it does in the games, being clearly seen from as far away as Pallet Town.

Ash and his friends have visited Mt. Moon twice. Once was in Clefairy and the Moon Stone, when they helped Seymour protect the Clefairy from Team Rocket and watched many of them evolve into Clefable due to exposure to falling Moon Stones. Also, it was here in this episode that Brock captured a Zubat.

Mt. Moon in Pokémon Origins

Later, Mt. Moon was also mentioned in The School of Hard Knocks, when Brock pulled out a bottle of Mt. Moon spring water from his Bag.

In A Real Cleffa-Hanger, they returned to Mt. Moon, encountering the Clefairy and Clefable again, and helping the Fairy Pokémon reunite with a young Cleffa.

In addition to the Clefairy family and Zubat, wild Paras and Sandshrew also reside here.

In Pokémon Origins

Mt. Moon was briefly seen in the Pokémon Origins episode File 2 - Cubone, as Red recalled battling a Fossil-crazy Super Nerd there.

In the manga

In the Pokémon Adventures manga

Mt. Moon is first visited in Raging Rhydon; however, it is first mentioned in the previous round, Gyarados Splashes In! by Professor Oak. The mountain consists of several interconnected caves, which are the home of wild Pokémon like Zubat, Diglett and Geodude. Its importance resides in being the place where the Moon Stone can be found. For this reason, Red and Misty enter Mt. Moon. Here is where the first confrontation between Red and Team Rocket Grunts takes place. Pika battled Koga's Rhyhorn, but Koga injected Rhyhorn with a syringe which made it evolve into Rhydon. Pika hit a rock from the ceiling which sealed Team Rocket in. Mt. Moon is also where Red battles Bruno in the beginning of the Yellow arc.

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.

In the TCG

Mt. Moon as depicted in the TCG

In addition to its presence as a card, Mt. Moon has been featured in Area 3 of Extended Sheet 1 of the Vending Machine cards. The Pokémon shown in this area are Geodude, Paras, Clefairy, and Zubat.
