Seafloor Cavern

Seafloor Cavern is a location in Hoenn. It is located on Route 127, where a player must dive, locate the submarine that Team Aqua stole, resurface, and the player will be inside. At this time, the player must solve several difficult puzzles, defeat Team Aqua (Sapphire/Emerald) or Team Magma (Ruby)'s grunts and leader Archie (Team Aqua) or Maxie (Team Magma). At this time, the game's legendary, Kyogre in Sapphire as well as Emerald or Groudon in Ruby will escape (Kyogre can be caught later in the game in Emerald version). The player is then prompted to go to Sootopolis City and meet Steven and Wallace. The player is then forced by the game to enter the Cave of Origin and defeat or capture the legendary to battle Wallace in the Sootopolis Gym.
