Seafloor Cavern

The Seafloor Cavern (Japanese: かいていどうくつ Seabed Cavern) is a location in Hoenn, deep beneath the seas of Route 128. In order to reach it, players must have HM08 (Dive) and HM03 (Surf), as well as the proper badges (Balance Badge and Mind Badge) to use the moves outside of battle. Once inside, HM04 (Strength) and HM06 (Rock Smash) are also required.

The search for the cavern begins when Team Aqua (Sapphire/Emerald) or Team Magma (Ruby) steals a submarine from Captain Stern. In Ruby, the cavern is the home of Groudon, who sleeps at its deepest part, while in Sapphire and Emerald, Kyogre is the Pokémon who sleeps here, while Groudon's home (at least in Emerald) is within the Magma Hideout, deep inside of the caverns of Mt. Chimney.

The player's quest to find the villainous team begins almost immediately after winning their seventh badge. With a Pokémon that can dive underwater in their party, they can now navigate the maze of deep trenches on the routes of Hoenn's eastern sea. In the deepest one of them, smack dab in the middle of Route 128's pathway, is the entrance to the Seafloor Cavern, where the stolen submarine is parked.

After resurfacing inside the cave where the submarine is parked, players must navigate through the complex maze of tunnels to the deepest part, where the legendary Pokémon resides. Here they will also find the boss of the team that has stolen the submarine, Archie or Maxie, who will attempt to control the legendary Pokémon of his desire using one of the orbs found at the top of Mt. Pyre. However, the Pokémon will not respond well, and instead will escape, causing severe rain or sunlight, depending on which it is. In Emerald, both types of weather conditions appear, and they change after player takes enough steps (counting actions like using Fly)

From here, the player must go to Sootopolis City and into the Cave of Origin, either to catch the powerful legendary Pokémon (Ruby and Sapphire) or to talk to Wallace to deduce where Rayquaza is located (Emerald).
