How do you get to the rainforest on Minecraft?

Well its simple. Just go on create new world and go to more world options... once there type in the Word "Lost" and once you create the world simply go to the dirt with purpilish brown stuff on it. Keep following the stuff and you will find mushroom island p.s. i tried this on 1.2.4 and it worked. Im awesome
