Crystals are the most valuable treasures in Minecraft Fun â€“ a kind of the Minecraft adventure game. It is not only a dream of a young Minecraft man but also the primary target of all the Minecraft gamers. At the present, their place is at the end of a grotto, and the exit is locked by a mass of many small rocks. It is an extremely dangerous and fearful place because the Minecraft gamers can confront a skeleton any time. Letâ€™s get and make use of all 4 lumps of TNT in order to demolish the rocks. Finally, the Minecraft boys/girls are ready to begin an adventure and walk through a long distance from the cave to the place of 2 crystals. They can bump into anything such as farm, conveyor belt, the exit, ladder, etc. Go into the entrance and descend the ladder. Beware of the lava! Good luck!
