Mobs
Emerald Golem
The Emerald Golem is basically an Iron Golem powered up, with three times the amount of health and 2 times the amount attack damage. It will not attack you no matter what, but it will attack other players. The Emerald Golem is the same formation with the Iron Golem but with Emerald Blocks instead of Iron Blocks, thus making them much more costly.
Vampire Bats
These are a hostile type of Bat, they can spawn only in 7 > light levels. They also can only spawn with a block of dirt or stone on top of where they spawn. They cannot kill you. They deal less and less damage to you as you take more and more damage.
Warrior
Warriors are a neutral mob. They spawn with one of 6 skins (showing different types). The most common type is Archer, followed by Swordsman, Ranger, Pikeman, Warrior, and Phoenix. Their weapons, respectively, are Bow, Gold/Diamond Sword, Crossbow (another idea of mine), Pike (same), any of the above, and Fire Sword (another idea)
Phantom
The Phantom is a boss mob that holds a glowing Iron Hoe (enchanted to Sharpness VII) and an Iron Helmet (unenchanted). They can make their bottom half intangible from all weapons and also float into the air. If near an Enderman they make the Enderman teleport away, and all hostile mobs (excluding Spiders) run from them. They can also teleport closer to you. They have 220 health.
Legendary Dragon
This is a dragon that is multicolored and can fly and swim, but more commonly walks on land. It breaks weak blocks that it walks through (Wooden Planks, Dirt) and also breathes fire on nearby targets. They are a large mob, larger than Ghasts. They spawn naturally in Plains biomes in the Overworld, as well as sometimes in the Nether. The Overworld type have 300 health, while the Nether type have 150 health.
Spy
This is a human-type mob that can blend in with its surroundings. It is passive, but usually after sight of one hordes of zombies appear somewhere near your player.
Fake Cobblestone
This is a mob that hides in Cobblestone blocks, similar to Silverfish. It has only 10 health, but decent armor stats. It acts mainly the same as Silverfish, and can break through blocks.
Items
Fire Sword
The Fire Sword is a sword that is held and dropped by the Phoenix mob. It has 1337 uses (:P) and catches enemies that are hit by it on fire. You can also craft it with 5 Blaze Rods and 2 Magma Creams.
Pike
The Pike is a weapon held by Pikemen that has a slightly longer range than a sword and that can stun enemies. It also does less damage than a Stone Sword due to the other changes. It is crafted with 2 sticks and 1 Emerald in the Shovel formation.
Crossbow
The Crossbow is a weapon that Rangers hold. It is a faster version of a bow, and uses iron-tipped arrows. It is crafted with a bow and 2 Silver Ingots.
Silver Ingot
The Silver Ingot is from mining Silver Ore. It makes items and armor that are less durable than Iron items of the same type, but much more powerful.
Copper Ingot
The Copper Ingot is from mining Copper Ore. It makes items and armor that are more durable than Iron items of the same type, but are much less powerful. It can also be used to craft copper wire.
Steel Ingot
The Steel Ingot is from smelting Iron Ingots in a furnace. It can be used to craft Steel tools and armor (better than Iron) and also used to craft blast-resistant Steel Blocks and Girders.
Obsidian Spikes
They act like both Fences and Cactus. You get 1-9 of them from mining Obsidian, and they can be used to craft armor and tools that are better than Diamond.
Blaze Armor
Crafted with Blaze Rods, when you put the full set on it makes you able to shoot fireballs with Right-Click while holding nothing.
Blocks
Steel Blocks
These heavy-duty blocks can be mined by only a Diamond pickaxe and are immune to explosions. You get one by smelting an Iron Block or crafting together 9 Steel Ingots.
Steel Girders
These are basically Fences that are immune to explosions.
Silver and Copper blocks
Act the same as Gold blocks, are crafted by their respective ingots.
XP Block
Has a 1% chance of dropping from any of the new mobs, glows green.
Obsidian Fences
Crafted with Obsidian Spikes in the Fence formation.
In addition to all that:
An in-game screen recorder would be nice, as well as multiple references to "Troll Face" (e.g. a Troll Man mob and a Troll Face painting)
