There may be some way in custom world options in minecraft itself but I highly recommend downloading worldpainter (http://www.worldpainter.net), and making your own custom terrain. There are tons of great tutorials out there and it's fairly simple to use, you'll end up a with much better looking world with a bit of effort.
Hello fellow craftrz I was wondering if you guys could help me figure out a way to make an entire world water but generate some islands!
Thanks lads
