Route 128

Route 128, Underwater

Route 128 is situated between Route 127 to the north, Route 129 to the south, and Ever Grande City to the east. Captain Stern mentioned that he'd found an underwater cave here while exploring in his submarine. Team Aqua has now breached that same cavern with their stolen sub.

Seafloor Cavern

The long-forgotten Seafloor Cavern can only be reached from an underwater cave in the depths of Route 128. Archie has gone to great lengths to breach the seal that has protected this place for ages, in the hope of awakening the super-ancient Pokémon rumored to dwell here. He believes this Pokémon has the power to bring about the great future he desires, but the risks seem far too great.

Items
Item Location Games TM26 (Earthquake) Deepest Room, east of the doorway  E

Entrance

When you first enter the cavern, you find Captain Stern's sub moored beneath the waves. Rise to the surface and take the north doorway to the next room.

Room 1

This room features two boulders that hinder travel. Go northwest and clear the way with Rock Smash, then use Strength to move the first boulder southward. Head east and move the second boulder eastward. At this point, there are two paths forward. The northwest doorway leads directly to the southeast part of Room 4. The southeast doorway leads through Rooms 2 and 3 to the southwest part of Room 4.

Room 2

Head south to a fork in the road. Both tunnels lead into the next room, but the western tunnel serves as a shortcut.

Room 3

The doorway to the south merely leads back to the entrance. Instead, go through the northeast doorway.

Room 4

Use Strength or Rock Smash to clear a path, then move the west-central boulder to the northwest corner. The northwest doorway leads to Room 5, while the northeast doorway leads to Room 6.

Room 5

This room has many strong water currents. Surf out into the water and ride the currents to a calm spot a short distance to the northeast. Sail east to ride the current to a patch of calm water to the northeast. Go east again to follow the current around the rock outcropping to the west side of the room. Surf westward and take the current to the northwest doorway.

Room 6

This room has many strong water currents. Surf eastward along the south wall to the second current, which leads a short distance northward. Go north from here to reach the west side of the room. Sail north once more to follow the current back and forth on the room's north side. Climb onto shore and go through the northwest doorway.

Room 7

The room splits into two tunnels before converging near the next doorway. The room's east side is littered with boulders, while the west side is clear, aside from Shelly and an Aqua Grunt. She's looking for payback for what happened in the Weather Institute, and draws you into battle!

VS Shelly

Aqua Admin Shelly Seafloor Cavern Emerald Reward: $1480 Types: Water Dark Ability: Rough Skin Held item: None Sharpedo♀ Lv.37 Scary Face Normal   --       Crunch Dark   --       Screech Normal   --       Slash Normal   --       Type: Dark Unknown Ability: Intimidate Held item: None Mightyena♀ Lv.37 Roar Normal   --       Swagger Normal   --       Scary Face Normal   --       Take Down Normal   --

Room 8

There are a dozen boulders here to block progress. Start off by moving the south-central boulder one step northward and the other two southern-most boulders farther apart. Push the first boulder one step westward, then shove the middle boulder one step northward. Move the boulders on the left and right farther apart, then push both the north-northwest and north-northeast boulders to the north wall. Finally, push the middle boulder to either side to reach the doorway.

Deepest Room

Go east to find TM26 (Earthquake) on the room's highest level before continuing along the downward-sloping corridor. Team Aqua's driven leader, Archie suddenly runs up to you. Like Maxie did with Groudon, Archie has discovered the super-ancient Pokémon, Kyogre, and stands ready to restore the creature with his stolen Red Orb. With his plan so close to fruition, he's not about to let anything stop him, and drags you into battle.

VS Archie

Aqua Leader Archie Seafloor Cavern Emerald Reward: $3440 Type: Dark Unknown Ability: Intimidate Held item: None Mightyena♂ Lv.41 Roar Normal   --       Swagger Normal   --       Scary Face Normal   --       Take Down Normal   --       Types: Poison Flying Ability: Inner Focus Held item: None Crobat♂ Lv.41 Bite Dark   --       Wing Attack Flying   --       Confuse Ray Ghost   --       Air Cutter Flying   --       Types: Water Dark Ability: Rough Skin Held item: None Sharpedo♂ Lv.43 Screech Normal   --       Slash Normal   --       Taunt Dark   --       Swagger Normal   --

Even defeated, Archie reaffirms his intent to revive the super-ancient Pokémon. While talking, the Red Orb suddenly shines brightly, awakening Kyogre. Like Groudon before it, the Pokémon flees away. Just then, Archie receives an urgent call from his subordinates outside. The great energy generated by the legendary creature has altered and intensified Hoenn's weather as expected, but to dangerous, unforeseen levels. The weather's dramatic shift to heavy rain influences any battles on the region's east side. The massive downpours boost all Water moves and weaken all Fire moves. Maxie and a pair of his Grunts enter a moment later. He condemns Team Aqua's actions and tries to reason with Archie, who counters by criticizing Team Magma for disturbing Groudon.

Route 128

The group returns to the surface, where they witness the extreme weather firsthand. Kyogre's power has surpassed expectations, forcing Archie to grudgingly agree to work with Maxie to set things right. Once the others leave, Steven swoops down to assess the situation. He informs you that the oppressive weather seems to originate in Sootopolis City to the northwest. He's headed there to investigate, and suggests you do the same.
