Sweet berry bushes
  • Commonly found in taiga, taiga hills, and taiga mountains biomes.
  • Rarely found in snowy taiga, snowy taiga hills and snowy taiga mountains biomes.
  • Can be planted from sweet berries.
  • Have 4 stages of growth: 'sapling', 'no berries', 'some berries', and 'full berries'.
  • Drop 1–2 berries in younger stage, 2–3 in full growth stage.
    • They're harvested with right-click.
  • Support bonemeal usage.
  • They slow movement of all mobs in all stages of growth.
  • Any mob can stand inside them, but they deal damage similar to a cactus if the mob isn't standing still, as long as the bush has grown past the 'sapling' stage.


Sweet berries
  • Fill 2 (Hunger.svg) hunger points.
  • Can be planted in the ground and will grow into sweet berry bushes.
