new mobs and new boss for elements

To Mojang 

So far in Minecraft there has been 2 element mobs (the breeze and blaze). I feel you could add more elements which are water and Earth. The Earth mob could be called the landslide and the Water mob could be called the Whirlpool.

The landslide could look like the blaze,but green,and be surrounded by sticks and rocks (which are unobtainable) and have 5 hearts which  regen. When you slay this mob you get a new item called the infested stick. This can be used to make infested weapons using the regular items, but instead of a regular stick an infested stick is used. These infested weapons can do 2 more damage, and the infested sticks could look like they are wrapped in vines.

The Whirlpool could look like the blaze but be surrounded by a mini water-tornado with mist emitting from it. This mob could have 7 hearts which can only regenerate when it is close to water.When you slay this mob, you get a special enchantment book which when applied to a trident causes a trail of water behind it.

If you put all of the elemental mobs in the same room, they will all form into one new boss.This boss has a mixture of the all the elemental mob colours, and has 20 hearts (they regen).

Once you have defeated this boss,you get the element long sword, which has 4 different modes.If you activate the earth mode, whenever you mine dirt, a 3x3x3 hole is created.The water mode propels you  in water, air mode propels you 10 blocks in the air and fire mode leaves a trail of fire(active for ZL)thanks
