Here's the Minecraft seed for those who like to survive on the islands. You will spawn on the mainland, but not too far into the ocean there are four different islands, each with a different biome.
The first island at coordinates -808 -728 is made up of savanna, and it also has a village standing on top of it. The second one is a desert island located at coordinates -950 -250.
The third island is made of extreme hills at coordinates -750 200, and the last one is a mushroom island just a bit to the west at coordinates -1400 -250.
