Beaver & Beaver Dam (River)

The beaver is a new mob that can spawn beaver dams. The beaver is able to cut down wood, when it finds a tree it will begin to cut it down when it breaks a block the block will become sticks the beaver will pick up the sticks and either add it to the dam or put it in the dams chest. the beaver dam it self will after the dam will have a chest which will spawn with a loot pool of sticks, saplings, apples, iron ingots, sweet berries, pebbles (you would be able to skip across water or use as snow ball variant) or cobble stone, bones, books, and a max of one golden apple. Also if you toss anything into a river it will flow down stream and possibly end up in a beaver dam. I think this mob would be really cool and ya I hope you like my beaver concept.
