Rubble (Cave Monster)

Rubbles are like little boulders that live in caves and like to break stuff.

On occasion they will pound the blocks below them, turning dirt to coarse dirt, stone to cobblestone, and cobblestone to gravel.

In combat they don’t stand much of a threat, that is until they combine with their friends to grow bigger and stronger.
They can also pick up stone related items from the ground to grow bigger.

They can drop ores on occasion as well as pebbles.
Pebbles can be thrown, however not very far, to do minor damage. They can also be crafted together in a 3x3 to make gravel.
However 8 pebbles surrounding a bit of clay will make 8 cobblestone.

Why should rubbles be added?
Well first of all they’d be freaking cute and fun, but also because we all know that the caves will need some new life when the cave update is revealed at minecon live
