Sweet Berry Bush

A sweet berry bush is a plant which is used to obtain sweet berries.

Natural generation
Berry bushes commonly generate in all taiga variants (,, and ). In all snowy taiga variants (, and ) each chunk has $1/12$ chance to generate sweet berry bushes in patches.

Planting
Placing sweet berries on a grass block, dirt, podzol, coarse dirt or farmland will create a small sweet berry bush which after some time will become a fully grown sweet berry bush.

Sweet berries must be directly planted on the top of a valid block; unlike most blocks, targeting the side of a block which would result in it being placed on top of a valid block will not allow it to be placed.

Growth
A sweet berry bush will grow through four stages after it is planted. Its first growth stage is a small bush without any berries. It becomes a grown plant in its second stage, and will grow berries in its third and fourth growth stage. The bush doesn't need any light to grow. Using bone meal on it will increase its growth stage by 1. Although the bush can be placed on a 1 block high space, it will not grow unless there is an open air block above it.

Drops
Sweet berry bushes can be used to collect sweet berries. A single bush will drop 1-2 berries at its third stage of growth and 2-3 when fully grown. Harvesting is done by the bush, and will set it back to its second stage. Breaking it with a tool enchanted with Fortune will increase its drop maximum by 1 per level.

Damage
Sweet berry bushes can deal damage every 0.5 seconds to the player or other mobs (except foxes) that move or jump inside them, similar to a cactus, as long as the bush has grown past its first growth stage.

Movement
Mobs that move through sweet berry bushes will slow down to about 34.05% of their normal speed, similar to a cobweb, which slows down mobs to 15% of normal speed. This makes it impossible to jump a full block while inside the bush.

Also like Cobwebs, fall damage is negated by falling into these. However, there is a tick of vertical damage for movement through the Sweet Berry Bush.

Mob interaction
Foxes will run up to and eat any sweet berry bush in the second or third growth stage within a 16 block radius, setting the bush back to the first growth stage.
