Why You Should Add the Wetlands Biome to Minecraft

Dear Mojang, this is my honest opinion on things that I think you should add to minecraft.

First, I think that you should add a wetlands biome. Adding this would give you the opportunity to add lots of new mobs such as cranes, snapping turtles, american bitterns, snakes, dragonflies, alligators, and even platypuses! I really need a pet platypus. I'm aware of the lack of birds in minecraft, this could help you fix that. Many animals both dangerous and cute lurk in the long grass and murky water. Adding a savanna is also acceptable, you could add lions and stuff. Also, the ice biome is really boring, please add something new to it, maybe penguins, or seals, or a walrus that I could name Bartholomew the 3rd, just consider it. PLEASE.
