Dense swamp

Swamps are very under appreciated biomes and minecraft.  They are often found and walked over because there is nothing there to do.  Swamps in reality can be bautiful places full of wildlife. I propose a counterpart of the swamp, named "dense swamp", that could feature tall closely packed trees and many fallen logs (that can produce bridges going across streams. Streams would be small long bodies of water the would carry items along with them.  I think that dense swamp could be added along side frogs and snapping turtles. Which could be passive mobs unless provoked. They could have eggs similar to sea turtles, but they would be smaller and have the ability the kill fish.
