Bettering Swamps with new blocks and generation

So, lets talk swamps, Right now, swamps are honestly kinda sucky. So I say lets change that! With mangrove wood announced, I'll just say how the trees shape should look. They should be tall and towering, with their leaves only at the top. These trees will also be able to generate in water, as this also happens in real life. Swamps ground will be mostly flat, sometime with Muk patches spawning. These act like soulsand, but do damage to boot durability aswell. The player will also be slower in this then soulsand, and sink in more. I accidently put ducks here, oops! That's my ideas for the swamp, and I hope you enjoyed!
