Wetland

It is a biome that looks like a combination of swamps and plains, and is characterized by the production of a large amount of water, mud, and moss.
Also, many grasses are produced on the moss, but no tree is produced.
Rice that is only available in this biome is produced, and that rice can be used as rice.
Frogs and tropical fish will appear in this biome, but both eels and otters will appear as new mobs.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
