Obsidien

Obsidien is made by lava and water getting mixed together. and you can use obsidien to make an Ender Portal along with flint and steal. and the only way to brake Obsidien is too mine it with a Diamond Pick axe.

Gardens

ok to get a Garden you need a hoe and if your wondering how to craft a hoe there will be a link to a video Down below showing you how to farm wheet and make a hoe. so once you have your hoe your gonna want to right click with it on some grass or dirt and then right click with your seeds where you Right clicked with your hoe. it could be melon seeds pumpkin seeds or just plain seeds (the plain seeds our wheet seeds) and your seeds won't grow if their not next to water or if the seeds don't have Enough Light.
