I dont work for mojang but i think ideas from other people will help to!post ideas for tools,mobs,blocks,and anything else you can think of.Ideas i came up with are aliens,natrul disaters,dieases,more types of mobs you can domesdact,npc characters,mutants from radoion,and more undead mobs such as a skeleton with a sword,maybe a ender pig which makes ender porkchops wich restore 5 hearts,planes,musket rifes,a single player chat bar for talking to npc characters,active npc mineshafts,a dimmsem the moon you need a cobblestone portal which you turn on by flint and steel (like nether portals),and npc labs and other npc buildings.
