Regrowth
The Regrowth mod introduces new dynamics to the Minecraft world, making the environment more alive and evolving. Villagers become true masters of their settlements: they independently cut grass, remove foliage that obstructs road movement (while leaving player-placed leaves untouched), repair road surfaces, build walls corresponding to the biome, and improve lighting around their homes.
Animals in the game also gain new abilities: they can feed on grass, and as they move across the territory, they contribute to its restoration, leaving seeds behind. Coral reefs now slowly regenerate, making underwater ecosystems more resilient.
The mod also affects mobs: creepers can hide in tall grass, zombies accidentally knock over torches when bumping into them, and skeletons stimulate the growth of huge underground mushrooms, adding mystery to the world.
