Berries++
From Wings of Fire: The New World Wiki
Berries Plus Plus (otherwise stylised as Berries++) is a Minecraft data pack created by iHeron and Stonley that adds in over two dozen custom sweet berries and glow berries to the game. Textures for Berries++ were created by iHeron and Fog and implemented into Dragonspeak, the server's custom resource pack.
Obtaining
All Berries++ custom berries are able to be harvested in the respective manners of their base item (e.g. blueberries can be collected from sweet berries, honeyberries can be collected from glow berries, etc.). Holding bonemeal while attempting to harvest either sweet berries or glow berries will not trigger the harvest mechanic, and as such will only yield the respective vanilla item.
