This city was originally founded to protect the Great Marsh. It has grown naturally over the years. The Gym is a good example of the abundant water resources available to the city. There is a lookout that affords views of the Great Marsh. The gates to the Safari Zone are also here.
Pastoria City (Japanese: ノモセシティNomose City) is a city in the region of Sinnoh. It is also the home of the Move Reminder, the Scarf Guy and the Sinnoh region's Safari Zone. It is a city on the edge of a giant swamp, known as the Great Marsh. The marsh was once part of the sea, which drained away over time leaving the marshland. There are rare Pokémon only found in the swamps. The Great Marsh keeps the weather cool in the summertime, making it an ideal town for Water Pokémon. Croagunk is one of the rare Pokémon that can be found in the swamp in Pokémon Diamond, Pearl, and Platinum.
The Marsh City (Japanese: だいしつげんと いきる まちTown that lives with the Great Marsh.)
The Great Marsh is an area located right to the north of Pastoria City. It is the main attraction of Pastoria City that gets many visitors and Trainers coming from around the area. The Great Marsh contains some Pokémon that cannot be found elsewhere in Sinnoh. It is filled with marshy areas, which are inhabited by wild Pokémon. Much like other Pokémon preserves in Kanto and Hoenn, the Great Marsh features a Safari Game in which Trainers pay 500 for 30 Safari Balls and a limited amount of steps (500) to catch as many Pokémon as they can. When a wild Pokémon appears, no Pokémon may be sent out to battle it: catching Pokémon here, as in all Safari Zones, requires sheer luck. There are four options in the battle screen: Throw a Safari Ball, throw Bait, throw Mud, and run away. Throwing Bait makes a Pokémon less likely to run, but makes it harder to catch; while throwing Mud does the reverse, making it easier to catch but more likely to run. Each day, a special type of Pokémon which can only be found on one day, will change, therefore, to get a new set, players must wait a day. These Pokémon will appear randomly in one of the six areas, some may not appear for a while, while others appear several days in a row or in multiple areas on the same day. Some may not appear until after getting the National Pokédex. The only way to tell which changing Pokémon is available in the areas for the day is to use the lookout upstairs from the entrance.
The Move Reminder allows Pokémon to relearn any move that they were able to learn at an earlier level than the one they are currently at, or ones from that level. Certain Pokémon have moves that may only be obtained in this fashion. The Move Reminder resides in a house northeast of the Poké Mart and will teach a Pokémon a move it could have previously learned but has not, in exchange for a Heart Scale. These may be obtained from the Underground, from the man in the Pokémon News PressPt, or from wild Luvdisc after the National Pokédex is acquired.
The Scarf Guy lives in Pastoria City, in the house nearest to the Route 213 exit. The Scarf Guy checks a Pokémon's condition to see if it is worthy of a Scarf. If the Pokémon's condition is at its maximum value in an area, he will give out the corresponding Scarf to that Pokémon. If not, he will tell the player to improve its condition with Poffins. The Scarf Guy lives with his sister and a Pachirisu. His girlfriend is the Massage Girl in Veilstone City, whom he keeps in contact with through mail, which he lets Pokémon deliver.
The Pastoria Gym is the official Gym of Pastoria City. It is based on Water-typePokémon. The Gym Leader is Crasher Wake. The Pastoria Gym is a large indoor swimming pool with numerous floating platforms. Switches on the floor of the pool raise and lower the water between three levels. To get to the Gym Leader, the switches must be hit in a certain order so that a path will be formed with the floating platforms. For defeating Crasher Wake, Trainers receive the Fen Badge, TM55 (Brine), and the ability to use Defog in Diamond and Pearl and Surf in Platinum Version outside of battle.
Ash and his friends first arrived in Pastoria City in Cream of the Croagunk Crop!, where Ash demanded to have a Gymbattle but was refused one due to the Crasher Wake's role in the Pastoria Croagunk Festival. The city's residents honor Croagunk as guardians of the Pastoria Great Marsh and treat them with massive respect. Each household raises one Croagunk with great reverence and care, and each year, all people gather at the festival to choose the Croagunk champion of the year. The winner receives a crown encrusted with a beautiful diamond and pearl. In the episode, the Croagunk champion was Nurse Joy's Croagunk, defeating the defending champion Hamilton. In A Crasher Course in Power!, Ash won against Crasher Wake, earning him the Fen Badge.
The anime also featured the Great Marsh, seen as a vast area filled with long grass, mud, and numerous puddles. It also showed a long boardwalk and a train to transport people and Pokémon across.
Southeast of the city, there are two ships, but they have no known use for transportation.
In Platinum, if the player stands behind the Croagunk Wall with the player's head sticking out of it, a wild Croagunk will come, but it will just cry and walk into the Great Marsh building.
Standing right outside the Move Reminder's house is a man who claims to be standing "smack-dab in the middle of town." However, according to the map, he is placed four steps down and five steps to the right of the true center of town.
Upon arriving in Pastoria, a Team Galactic grunt will refer to the player as a "little bugger". Despite the game being acceptable for 'Everyone', 'bugger' is an expletive in some parts of the English-speaking world. This line was removed from the European release.
