A MUDDY UPDATE: SWAMP ZOMBIE+SWAMP VILLAGE+DUCKS+CATTAIL

This could be a future update for the game, that would focus on improving the swamps, biomes that has a great but unexplored potential:

• The Ducks would be a new mob that would spawn naturally on lakes, rivers and, of coure, swamps. They would have their baby version, would swim a little bit underwater to hunt and kill salmons, and would sleep on land. If you kill them, they would drop duck feet, that would be useful to swim fast;
• The cattail would be a new plant specie that would spawn just like ducks, giving a better and more varied visual to the game;
• It's a perfect biome to receive a village: the trees are far from each other, the wood color matches (they're very cool), and this is one of the biomes with the most unexplored potential in all Minecraft: they don't have anything cool to explore and see. With the village, this problem would be solved;
• If this biome has it's own skeleton variant, why can't it have it's own zombie, too? It would cause the same effect as the it's skeleton arrow and would throw slime balls, giving the game a bigger diversity.
