Green Mushroom, Gravishroom stew and anti gravity (Green Netherwart Forest)

Green mushrooms can only be found in the Green Netherwart forest biome (link in the description). These mushrooms are like the other nether mushrooms.

Four green mushrooms and four different mushrooms can make gravishroom stew. A stew that gives you sixty seconds of anti gravity and ten seconds of slow falling.

Anti gravity is an effect that reverses your gravity. A useful effect that can help you navigate the Green Netherwart Forest Biome and other parts of the Nether. It can also be used as a fun little effect in minigames if the designer wanted to add the effect.
