Minecraft wiki entry for Skyblock, associated text: Your first day will mainly depend on the skyblock map. If you have any grass or flowers, mine them and try to get at least one seed. Then, break the dirt on your island, leave at least a few grass blocks. Place the dirt around the tree so that it catches the dropped saplings. Chop down the tree and make a crafting table and wooden pickaxe. Catch the saplings and replant them. If you have a chest, open it and check the items. You usually start out with a few crops like sugar cane, melons, and pumpkins, some obsidian for a portal. Some maps also give you 2 turtle eggs since you cannot find them anywhere else. There is also a bucket of lava and ice. To make a cobblestone generator, dig a one block deep T-shaped hole. Put a block in the center, water and lava on two others slots. Break the center block, get in the last slot, and break the cobblestone that forms. Make sure that the blocks that surround the lava are not flammable, or they will burn. Mine as much cobblestone as you can and make a full set of stone tools. Make a small shelter out of wood or cobblestone to prevent phantoms and other monsters.
