The quest grove is a landmark only found in the Enchanted forest. The landmark will contain a very large ram and a dispenser with some 3 wool. You must give the Ram all 16 types of wool. Right clicking on him with a piece of wool will make a colour appear on his fur of the wool you gave him. Once you have all 16 types of wool on the Ram, you will recieve a diamond block, gold block, iron block and a crumble horn. Be warned the Ram only has 5 hearts of life. A single bow shot could kill him.
