What?

Nulberries are small blue fruit. They can be cultivated like sweet berries.
They're not very nutritive, but when eaten they remove any potion effects, like Milk, but considerably easier to carry.

Where?

Nulberry bushes can be found infrequently in wooded biomes and snowy biomes, in small patches.

Why?

This is my first minecraft modding project done from scratch and I just wanted to make something cute with whatever assets I had lying around.
