O.K Guys
I am seriously stuck on the Seafloor Cavern on Ruby I don't know what to do next...Do you have to move the boulders a certain way?
Anyway does anyone know a guide that will clearly explain this to me?
You came to the right place! This is for Emerald, but I am pretty sure it is the same with Ruby/Sapphire. Here we go:
To get through this dungeon, you will need Strength and Rock Smash. If you do not have both on your team, return to Mossdeep and pick up Pokémon until you have them both. You're going to want to pick up a few Max Repels if you're short on them. I'd say you'll want at least 3 or 4, unless you plan on fighting the wild Pokémon. Then surf straight south to Route 128, to the large square. Dive in front and enter the cavern.
The sub is here. Looks like Team Aqua's here. Surface and go up into the cave. Go up and activate Strength. Crush the small rock and push the boulder either up or down - NOT right. Go right and push the boulder. You'll see a copule of Team Aqua Grunts. You can skip them both, but what's the fun in that? Up the steps, fight the other one.
NOTE: This dungeon can get very confusing. There are doors that take you to two different rooms, and you may feel like I'm skipping a lot, but I'm just saving you a LOT of wasted time.
I'm sure you can see the team battle down there. If you don't want to fight them, skip the next paragraph, and start after the words "Right here!" There are no items to be obtained.
Go down into the room. Go down and activate Strength. Of the upper two boulders, push the top one to the wall. Then push the bottom one down and smash the rock. Go in the door and jump the ledge. See the grunt? There's another one below him to team battle - sneak around get between them if you want. Jump the ledge and go all the way to the bottom. Go in the door. You're back at the beginning. Now you start all over. Activate Strength from the left, smash the rock, push the boulder up or down, go right, push the boulder right.
***Right here!***
Go left and up through the door. Go up and activate Strength. Smash the rock near the door you just came out of. Go push the upper left boulder up and go in the door. Enter any of the water currents, you will end up at the same spot. Go either down or right. Now go right. IGNORE THE CAVE. GO LEFT. Now go up, land, and into the cave.
There's a Double Battle here. It's much easier to fight them, but for the wimps out there, there's a ridiculously easy boulder puzzle to figure out. Imagine the boulders are numbered, starting with #1 at the top and increment going down. Activate Strength and push #7 to the left. Push #4 up, then push #3 up twice. Push #1 left and you're done.
For those who don't feel like wasting their time doing that, just fight.
In the next room, you'll find another boulder, but this time it's forced. It isn't all that hard. Push boulder 11 up. Boulder 0 goes left, 12 goes right. Boulder 11 goes left/right, 6 goes up. Boulder 5 goes left, 7 goes right, 2 and 3 both go up, 11 goes off to the side.
The path is misty. Pick up the item ball for TM26, Earthquake.
We've seen this somewhere before... following a path to a large beast thing. This time, there's no one there, but a heal and save is still recommended. When you're ready, step in front of the creature.
That is it.
