Big Brain
The Big Brain mod fundamentally improves the artificial intelligence of various creatures in Minecraft, making their behavior more intelligent and realistic.
Smart Animals
Most land animals (except cats and foxes) now seek shelter during rain or at night. When one member of the herd is attacked, the other animals begin to panic and warn their relatives of danger.
Pig Features
Unlike other animals that provide useful resources (cows - leather for armor, chickens - feathers for arrows, sheep - wool for construction), pigs previously had no special advantages. Now pigs have an increased litter size - from 2 to 6 piglets, making their breeding more profitable for farm operations.

Improved Pillagers
The combat system of pillagers has become more thoughtful. They now retreat while reloading crossbows and approach the player when using a multishot crossbow. Patrol leaders have a 50% chance to spawn with a spyglass, allowing them to spot the player from a greater distance.

Snow Golems
Snowballs now apply a freezing effect for 5 seconds, which can accumulate with consecutive hits.

General Improvements for All Mobs
- Blindness reduces mobs' vision range by 90%
- Fixed the bug with melee mobs resetting attack cooldown
- Mobs capable of opening doors can now open fence gates
- Bow-wielding mobs changed tactics: they stand still, fire three shots, then change position
- Humanoid mobs (zombies, piglins) learned to jump over obstacles


Special Abilities
Husks burrow into the ground when they see the player, then grab and pull them down. The attack can be interrupted by dealing significant damage during burrowing, or by moving to higher ground.

Ocelots attack creepers, parrots, and phantoms, gaining a useful role in the game.
Sheep run away from wolves instead of indifferent behavior.
Polar bears hunt fish.
All mod features are configurable through configuration files.
