Fox

Foxes are nocturnal passive mobs that spawn commonly in taiga and snowy taiga biomes.

Spawning
1-3 foxes will spawn in taiga and snowy taiga biomes and sometimes in taiga villages. They will spawn more commonly at night time, sleeping in the forests, sometimes holding emeralds. 16.6% will be babies.

Behavior
Foxes are nocturnal, sleeping in the morning and being active at night. They move quickly, about the same speed as ocelots, and will flee from any nearby players. If any food item is on the ground near a fox, it will travel to it and pick it up. This behavior does not seem limited to food and animal products, as foxes have been sighted picking up and carrying logs, dirt, TNT, and emeralds. Foxes are fed with meat or berries.

When sweet berries are on two foxes, the foxes will breed, producing a baby fox. The baby fox will "trust" the player, and never run away from them.

Foxes will attack chickens and rabbits, jumping over fences and walls when necessary. Wolves are aggressive towards foxes.

When spawned in a snowy biome, foxes will be white in color.

If there is a stage 3 or 4 Sweet Berry Bush within a 16 block radius, a Fox will sprint towards it, harvest and eat the berries.
