Sweet Berry Bush

A sweet berry bush is a plant that produces 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 creates a small sweet berry bush that eventually becomes a fully grown sweet berry bush.

Growth
A sweet berry bush grows 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 produces berries in its third and fourth growth stage. The bush doesn't need any light to grow. Using bone meal on it increases its growth stage by 1. Although the bush can be placed on a 1 block high space, it cannot grow without an open air block above it.

Drops
Sweet berry bushes can be used to collect sweet berries. When harvested, a single bush drops 1-2 berries at its third stage of growth and 2-3 when fully grown. Harvesting is done by the bush, resetting the bush to its second stage. Breaking it with a tool enchanted with Fortune increases 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 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.

Preventing fall damage
$$, a sweet berry bush of any growth stage prevents a player or mob from taking any fall damage. However, for growth stages after stage one, the bush still deals a tick of damage due to the vertical movement through the bush.

Mob interaction
Foxes run toward 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.

Bees
Bees will "pollinate" sweet berry bushes, and will then increase the honey level in beehives and bee nests by 1.
