Mangrove Witch Dungeon

This is not just a Witch Hut made out of Mangrove Wood, here's the Idea:

This is a Unique Witch Hut which spawns in the center of the Mangrove Forest Biome, It looks like a creepy, abandon, and small house. Inside of it, there are a few black cats and cauldron's just like a regular witch hut. But, 1-2 witches could live in this section of the structure

There is an 80% chance that a room spawns inside of it with an entrance to a lower level, this is a small dungeon. This is just a slightly bigger version of the regular small dungeon but with a few extra rooms and traps.

The entire structure is engrossed in foliage all around to keep that tight feel of the biome.

This would make the Mangrove Forest a little tighter and would add to the overall feel to the biome.
