Union Cave

Union Cave (Japanese: つながりのどうくつ Linking Cave) is a cave located in the Johto region. The main cave divides Route 32 from Route 33, though two other exits in the basement levels of the cave lead to the Ruins of Alph. A wild Lapras can also be encountered deep in the cave every Friday after Morty has been defeated (as Surf is required to get to it).

Geography

Union Cave is a simple cave, with many pools of water. The main floor has two different entrances to lower floor in the southern area^GSC/opposite ends of the cave^HGSS. The upper one leads to B1F, which, after crossing the pond, will lead to the Ruins of Alph. The lower one leads to a small hallway, which also has a pond, and another entrance to B2F. The lowest level of the cave has several ponds, the southern-most containing, on Fridays, a Lapras.

Union Cave in Pokémon Gold & Silver: The Golden Boys

Gold, Silver & Crystal chapter

Union Cave appeared in Off Course with Corsola, where Crystal was traveling through the cave to get to the western part of Johto. While going through the cave, she noticed a Magneton, which was not native to the area. She was then attacked by a group of Magneton, all of which belonged to Lt. Surge, who had ordered them to catch any wild Pokémon passing by. When the Gym Leader himself arrived, he saw that his Poké Ball trap hadn't caught anything, leading him to believe that the commotion was just a false alarm. He then proceeded to exit the cave through an underwater tunnel, not noticing that his Magneton had dropped the unconscious Crystal into his submarine.

Pokémon Gold & Silver: The Golden Boys

Union Cave appeared in Extreme Power!! The Friday Pokémon where Black tried to capture a Lapras but failed. Gold took in Black's Bayleef after Black left it behind.

Pokémon Pocket Monsters

Union Cave appeared in Escape from Magma!? of Pokémon Pocket Monsters. Red and his Pokémon went there by traveling on a Lapras. Inside, Giovanni and some Team Rocket Grunts took over the cave by building an amusement park. As Red and his Pokémon went in, it turned out to be a trap as Giovanni sealed the entrance. The group managed to escape when Clefairy's digger drill dug a hole. However, it took them deeper in the cave where Giovanni found them and summoned his Slugma from a lava pit.
