Hello everyone, this is my first 'ideas' blog. I have more ideas, so if you want to see them in another blog just let me know by showing some love and commenting. Lets start!

 1) A Knight Mob - The Knight Mob would spawn in Dark Oak Forests. He wouldn't be rare, but he also wouldn't be extremely common (like a wolf). The Knight would have iron armor and an iron sword. He kills any non-peaceful mobs in sight excluding the Wither. He would offer to protect you for a trade of emeralds, gold, iron, or something along those lines. You would be able to have him stay at your house if you were going to go on a mining trip near lava, and he wouldn't follow you into the Nether or the End, making him slightly balanced.

 2) Naturally Generated Burn Houses - These houses would look as if they were burnt and would spawn naturally in plains. They would be made of bricks and wood, and have a chest inside. The chest would have nothing special, so getting a piece of iron in one would be quite lucky.

 3) Natural Disasters - Extremely rare, natural disasters would occur around the world, somewhere within a 20 chunk radius of you (Not sure if thats too much, let me know in the comments!). Examples could be a tornado, blowing blocks into a certain direction and causing the player to fly high up, and fall to his death. Another example might be an earthquake. They would only cause a couple blocks of your house to collapse, but they would be able to change smooth stone to cobblestone!

 4) Mother Spider Boss - A slightly easier boss than the Wither or Ender Dragon, there would only be 10 dungeons in the world that had this boss inside. There would be no tracking system like the Eyes of Ender, but you could often find them if you found a large amount of spiders in one area during the night and dig down. Her only attack would be a swinging stinger attack, but she makes up for it by having random cobwebs around the room and spawning several cave spiders or normal spiders. After killed, the loot would be mostly string, but also some enchanted iron armor or enchanted iron tools.

 Well, to not make this too long, Im going to stop here. If you enjoyed and want to see more ideas, make sure to diamond and maybe even favorite? Bai!
