Slowpoke Well (Japanese: ヤドンのいどYadon Well) is a man-made cave located at the edge of Azalea Town. It is located just north-west of Route 33, first seen on the way to Azalea Town. The cave is home to a wide variety of wild Pokémon, but is unique for being the home of Azalea Town's Slowpoke, which they use as pets. It is said that a Slowpoke from the well ended a drought that plagued Azalea 400 years before the games' events by yawning.
Slowpoke Well is where the player first encounters the revived Team Rocket, who are cutting off the tails of Slowpoke to sell at their HQ in Mahogany Town. Before talking to Kurt in his house, there will be a Team Rocket grunt guarding the entrance of the well, and will not let anyone in. When entering Kurt's house for the first time, he will quickly run out after saying something about going to the Slowpoke Well. He will defeat the grunt at the entrance, then will fall into the well and injure his back. After Kurt is injured while trying to stop Team Rocket, the player has to defeat the Grunts and rescue the kidnapped Slowpoke.
There are two floors; the first one can be explored when Team Rocket attacks, whereas the other cannot be reached until later. Later in the game, after the player has acquired both Surf and Strength, they can explore the lower floor of the well. There is a man on an island who will give players a King's Rock if they talk to him.
The Slowpoke Well is located on the east side of Azalea Town, just north of Route 33. The well is a actually a large cave with many chambers. In Pokémon Gold, Silver, and Crystal, Slowpoke Well can be accessed to by going down a small flight of stairs into the dark cave below. In Pokémon HeartGold and SoulSilver, there is sloping ramp that winds around the well, slowly descending in an indented section of ground. The aesthetics of the well have also been updated to show a small, circular, brick well, which can only be entered by going straight into the hole of the well.
Upon entering the cave, there will be a small pool of water to the west, and a narrow passageway to the north. During the Team Rocket attack, the cave will be populated with Team Rocket grunts looking for battle. By traveling up and down the small ledge, the other side of the cave can be reached. From there, the path travels north, then west through a narrow strip between the wall of the well and rocks, finally traveling south to a pool of water deep within the cave. After surfing through the pool of water, there is a small island in the middle of the cave that has the stairs to the lower floor of the well.
The lower floor can only be accessed after the player has acquired both Surf and Strength. This section of the well enters from the ladder in the middle of the cave, on an island in an underground lake. By surfing around this floor, there is a man on an island who will give players a King's Rock if they talk to him, while TM18 (Rain Dance) can be found on the ground.
In Pokémon HeartGold and SoulSilver, the cave seems to have changed slightly. There are several map changes within the cave, including a new section coming from the first floor; a flight of stairs going down within the cave, traveling east shortly, then south.
