Mound (Cave Biome)

The Mound is a biome that spawns in-between the rarity of ice spikes and mooshroom island.

It looks like a Mound made up of coarse dirt, grass, dirt, and mud (a new block). The biome itself goes up above the clouds and will be covered in large wide ravines, wide caves, large open areas throughout the caves, and a lot of life growing inside, including trees, vines, bushes, and bugs. The caves will not be made of stone and will instead be made up of dirt, mud, coarse dirt, and grass. Since it's made of dirt it won't have stone ores and will instead host varients of the ores imbedded into the dirt. They will need to be mined with shovels instead.

The biome will not be able to spawn as big as most biomes and at it's maximum width will be around the size of 9 woodland mansions in a square.

Now onto the new stuff in the update.

Mud: Mud is the height of a normal block, but looks like a slimier darker dirt. It slows you down when you step on it like soul sand does, unlike soul you can counter the slowing effect with leather boots.

Inside the mound there will be lots of greenery, and greenery will need water. The inside of the mound will have plenty of that!

Mangrove trees: Mangrove trees will spawn inside pools of water that are in or near the bottom of a ravines. You can also find the off to the side of ravines in pools of water that covered by land but still have a light level that won't spawn enemies.

Leafhopper: The caves of the Mound are covered in vines and sometimes grass. But if you pay attention you can see bright green vines or grass. If you hit it a leafhopper might hop out! After that if you feed it an apple, carrot, potato, vines, or leaves it will be tamed and will follow you around. It will start hopping when other bugs are nearby. Leafhoppers are about the size of a silverfish.

Obviously spiders are in the Mound but what about another arachnid?

Scorpion: the scorpion is a hostile mob that only spawns in the desert, mesa, or in the Mound above the clouds. They will hide underground until you are near and will then pop out and try to poison you with a very deadly poison. If you manage to kill the scorpion you can get a scorpions tail, which can be used to severely poison an enemy but with very limited durability, only offering a couple of hits before it's gone.

Worms: worms are passive mobs that can be found in the Mound or Swamp. They have very low health so if you hit them they will die immediatly. They wont drop anything but if you have a bucket in your inventory you can right click worms to collect up to 16 in a bucket. Worms will improve the speed of fish coming to your fishing rod as well as make it alot lesslikely for you to get anything other than a fish. This effect can stack onto fishing enchantment.

Ants and fire ants: Ants will spawn on the outside of the Mound and will be nuetral. They are about the size of a spider and if attacked they will start attacking the player, dealing two hearts of damage.They will drop chiten which can be crafted into the blast resistant chiten block. If one ant is attacked all be ants will swarm the player. The fire ant is a rarer, bigger, hostile ant that will deal four hearts of damage and a low chance of getting the player on fire. Once killed the fire ant can drop 1-3 fire chiten which can be used to make a fire chiten block, which works simalarly to the magma block, except you can't avoid the damage by crouching and it is blast resistant. Fire ants will not cause other normal ants to swarm.

Mushrooms will spawn commonly in the Mound along with giant Mushrooms, but with this update comes a change to the giant mushrooms.

Mushroom stem: The stem of a mushroom can be mined like a log and will drop a mushroom stem, which can be used to craft fungal planks, a mushroom version of wood.

These planks could craft all the stuff wood can but in a bright white color with specks of light gray.

You can also click on the mushroom stem with an axe to make shaved mushroom stem.

Daub: you could make Daub by crafting mud with wheat. Daub could be a dyable, hardened clay like block of sorts, but instead of having a brown tint to it, it could just be a desaturated, noisier version of concrete.

What do you guys think? I know there would probably need to be a bit more features on the design of the outside of the Mound, but I'd like to leave that part to Mojang.
