Island Cave

The island cave is the cave that contains Regice in Generation III games and is accsesable if

1: you can read Braile

2: you find a way into that cave somewhere in between Pacifilog town and Slateport city

3 you bring a Wailord and a Relicanth

What you do is you go to Petalburg city, then go to the beach close to it and surf down and stay next to the left until you see a gap next to an island or something then, when on the other side of the rocks, go up until you see an island. if you didn't do the things above then there should've been a earthquake in that cave I was talking about, resulting in the entrance of that cave and 2 others. when you get inside, wait 2 minutes and anather entrance will open up, with Regice inside

Regice should be level 40 and knows

Superpower

I think Ice shard or Icy wind
