Seaside Cave

Seaside Cave (Japanese: 海辺の洞穴 Seaside Cave) is a cavern located between Route 21 and Undella Bay. It is accessible as soon as the player gets to Undella Town; however, Black Belt Rocky blocks the player from exploring further until Drayden has been defeated and the player has ridden Team Plasma from Opelucid City after they have frozen it. It is also the first area in the game where an HM is needed to proceed, with Surf being required on Route 21 or Undella Bay to reach this area.
