Steve is invited to participate in an elite building competition on Mushroom Island. Steve builds his dream house to impress the judges, but just as they begin judging, the island is overrun with Endermen. Mushroom islands are known for not having hostile mobs, so everyone knows it's the work of a griefer. Is it one of the contestants? Nobody knows, but they all have to work together to battle this invasion of the Endermen.

Steve and his friends are back at the wheat farm trying to find a way to secure their crops from hostile mobs when their old friend Georgia comes to them for help. Georgia's village is in the middle of a serious skeleton attack. The skeletons appear at dawn, and nobody can go to bed without risking death. Steve and the gang agree to help, but the journey to Georgia's village isn't easy, especially with a new batch of rainbow griefers on their trail....

Going to this fabled mountain, rumored to contain an endless supply of diamonds, is every treasure hunter's dream. Many believe the mountain doesn't exist, and although Steve is doubtful about the map's authenticity, the gang convinces Steve and Kyra to embark on a journey to find this magical mountain....
