Bamboo/desert snakes

I think that Mojang should add bamboo snakes. They have a 4% chance of spawning when a player mines a bamboo stalk. They drop 5 experience points. They could also drop a snake fang that could be used to craft 2 poison arrows by taking the place of the flint in the crafting recipe. A variant of this creature is the desert version which could spawn in or around desert bushes and/or cactus. The snakes in the bamboo are green and the desert version is brown and has diamond patterns on it's back. Both types of snakes alert others to come and help them when they are attacked. Bamboo snakes will slither out of nearby stalks to attack - while desert snakes fall out of cacti/dead bushes to attack. Both variants should be skinny and hard to hit with arrows.
