This is one of the two entrances to Oppel Cave, a place where many Pokémon often can be found that aren't available anywhere else in the region of Kimchi. To pass through here, you must use Flash as well as Rock Smash. The Pokémon aren't like many Pokémon on the other routes. They are more hostile towards those that invade their territory, and will attack you if you get too close. The Ghost-types use the darkness of the damp cave and trick unsuspecting travelers into getting into trouble with other Pokémon.
Wild Pokémon native to the area:
Zubat, Golbat, Geodude, Onix, Machop, Misdreavus, Meditite, Gastly, Whismur, Loudred, Sableye, Mawile, Dwebble, Crustle, Klink, Klang, Noibat
HM's required to pass through:
Flash, Rock Smash for a shortcut to the Route 7 Entrance
[Black colored Pokémon can be caught with a Poké Ball, Blue colored Pokémon need to be caught with a Great Ball, and Red colored Pokémon need to be caught with an Ultra Ball.]
