Roofed forest Bush (read description)

I think the roofed forest should be really dark and stuff like that. But the main point I will talk about is the Roofed forest bush. since more mobs will spawn inside the biome during the day, I think there should be a useful foliage in the biome which would be added in lets say something like the Wild Update.

Roofed forest bush purpose : it is a 2 block high bush that can even spawn 3-5 blocks high. You can walk inside of the bush but it will slightly slow you down and make noise / only reason for this is the skulk sensor. But when inside of it, normal mobs like zombies and skeletons won't see you. And if you get the attention of a mob and make it walk inside of the bush then it can get tangled up, this is dangerous for your pet. 

These bushes dont spawn in the "outskirts" of the roofed forest biome and only will grow in light level 0. 

Drops / uses : when dug with shears you have the chance to get thorns which can be crafted into different types of arrows which travel slower with more drop but hit harder.

- The bush can be used to hide from monsters and get them stuck, used to get thorns, you might get pricked if you stay in for too long, skeletons in the biome use the thorn arrows, lots of mobs spawn in the roofed forest biome, and also things not included above this for the biome itself like less normal trees, make the dark oak trees bigger, and darker.

There might be some things with the idea that need improving but that's ok because this is mc feedback
