Seafoam Islands

You can't get through Seafoam Island unless you have a Pokémon that knows Strength. So remember to bring it. This underground maze looks mighty confusing, but it's actually not that bad. The idea is to use your Strength ability to move boulders out of the way and drop them into holes in the floor. This will make them fall to a lower level and form a dam -- which stops the strong current and lets you safely swim around. If you mess up and move a boulder into a bad spot, simply exit the room to find the boulder reset to it's original position. After you enter the cave, go to the east and push the boulder into the hole to the north of it. Now go back to the steps to the north of the entrance and go up. Instead of going down the ladder in front of you, continue on to the east and go down the steps there. Push the boulder down the hole, then take the ladder next to the hole down to the basement. You will now see the rock you pushed through from above lying on the ground. Push it into the next hole and head back up. You should now take the ladder you originally passed by. You will emerge on top of a plateau. Make your way south, then east, up the steps and all the way north. Now go to the right and go down the steps. Voila. There's that first boulder you pushed down. Push it into the next hole and head back up onto the plateau and go back to the very northwestern corner of this room. There, you will find another ladder (it's close to the ladder you original came down from). Go down and head east to find your boulder again. Push it into the hole and head back up. Go southand east and back onto the second plateau. Go down the ladder, then head west and take the steps down leading to the ladder in the southwestern corner of this room. Confused yet? It will get worse. You should now emerge from the ladder just to the north of another boulder. To get there, head to the east and down. There are four boulders here that you need to push around, two of which have to be pushed into holes. Here's the easy way to do it. Start with the right boulder and push it up two squares. Now you can push the second boulder from the right down. Push it one square down only, then two squares to the left. Now walk around the hole to the other site to knock it down into the hole. Next, push the boulder just to the north of you all the way to the left. You can now drop the last boulder into the hole. Go up the steps and continue on northwest until you see steps leading down to a small area with another ladder. Take those down to the lowest level. Make your way to the northeastern corner of this area and use the ladder to go back up (it's near a sign). Take the next ladder up as well. You will now be able to push the last boulder into the hole. Now go back down the two ladders -- you are ready for a swim. With the boulders blocking the current, you can now go to the westernmost part of this area and walk down the steps into the water. Swim to the very north until you see a bird Pokémon perched on a small island. This is your chance to catch another legendary bird Pokémon. Articuno can be found in the northwest corner of the lowest level of this dungeon. It's a lot easier to catch than Zapdos since you can use Electric attacks to bring it's HP down. Be sure to save your game before you try to catch Articuno as it can take a couple of tries (and a lot of Ultra Balls) to get it. But catch it you must. It's already at level 50 and will learn the powerful Ice attack Blizzard at level 51. After you're done, go back to the ladder you just passed and take it up. You should now be on the level where you pushed around the four blocks. Go south, but don't take the ladder you see there -- instead go east and up, then descend the steps into the water and swim over to the right. Walk up the steps and go south to find a new ladder. This is the way out.
