This is a flat water world that has flat bedrock underneath 100 blocks high of water...this is very usefull for certain megabuilds... well good luck. BTW if you go in survival your probably gonna not get much use out of it :P
Yes I know this isn't a build but i've been looking for one for quite a while and I couldn't find any so i made my own. This makes it possible for you to make your own places to put on planetminecraft. I'M SORRY FOR THE THAT IT IS NOW MEDIAFIRE.
