Goopool Swamp is a damp and foggy area, with areas that the player must wade through thick swamp waters and even use the Surfboard to trek across. It is somewhat maze-like; there are a lot of ups and downs that make this place easy for travelers to become lost in.
Towards the end of the swamp is a Spooky Cabin, with a graveyard in its backyard.
Places of Interest
After having battled Lunar Commander Scarlett and her two Lunar Grunts, the player will be able to access Spooky Cabin. The cabin is neglected and in disarray, with several Ghost-type Pokémon now making it their home.
The player will find papers and notebooks inside, telling the story of an old man who experienced the deaths of his large family: his wife, his six children, and his three Pokémon. He appeared to become obsessed with bringing them back. The bookshelves are loaded with books on ghosts as well as his research notes on what he has titled, "Reanimation Project." On the wall, the player can see the entire family portrait.
When the player steps out the back door and into the graveyard, a ghost with the appearance of an old man appears. He judges the player has a pure heart and, before disappearing, tells the player to choose a gravestone as theirs. The three gravestones in the back are of three Pokémon: Scrow, Gaslit, and Dozand. The player may choose one gravestone to activate a battle and capture a Pokémon. After capture, all three gravestones do nothing else. The rest of the headstones in the graveyard of those of the old man's family: his wife, Aurelia; his sons, Jim, John, and Jack; and his daughters, Agnes, Aurora, and Amira. To the right, the player can find a Spell Tag.
After defeating the Elite Four, the player can return to Spooky Cabin to find the ghost of the old man wandering around. He will inform you that the other two Pokémon (those you did not pick the first time around) have returned to the graveyard for you to catch and then disappear forever.
