Seafoam Islands (B1F)
Where?
On Route 21, between Cinnabar Island and Fuchsia City. From Cinnabar Island, surf right. A short way in, there will be a bit of sand you can step onto; do so and walk on right, taking the lower path where it splits. Once you get to the end, surf onwards to the right and then enter the cave above you. This is 1F.
If you now go down the stairs in the top left, that's B1F. Move the first rock above to the left with Strength and go up the stairs onto the platform on the left. Walk on left and down the ladder on the left end. This is B2F. Now head down the stairs on the left, go down below the ice floor and then up to slide across it, slide across the ice floor on the right, position yourself to be just above the trainer on the ice floor below below and then slide down, then to the right once you hit him. Then go down the ladder on the right to B3F.
Finally, from there, go left below the ice floor there and slide up straight into the near two ice blocks. Then go back on the right side of the ice floor and slide left into the final block and follow after it as it locks into place by the wall. From there, slide up and head left again and go down the ladder there to B4F.
Notes
Like in Red, Blue and Yellow, Articuno (level 50) resides deep within Seafoam Islands. Go to B4F as instructed above, surf down into the water below you, head right and then up, up onto the platform, off to the right and back into the water down the stairs on the right, then on down and to the right, up the stairs onto the next platform and then up the ladder there. Now go up the ladder on the left, head right over the bridge and then down the ladder, down the other ladder above, and then down into the water there. Finally, surf on to the left until you get to a large platform above you. Articuno is standing there, ready to face you.
