The minecraft seed shazoom is a desert island scenario. You spawn on a small island with one tree, some squid swimming nearby, and a passage leading under the island. Unfortunately the passage does not lead anywhere. There is, however, a huge cave system beneath the island if you dig down far enough. Plenty of ores, and certainly enough obsidian to get you to the nether. Its either that of build a boat a adventure in the ocean, but its a good distance before you will hit any land.
