Fermentangy is a moldy lemon alter ego spawned from Luna Song (aka. MoonchildOfTheNorthForest) stumbling across a mysterious bowl of lemons in the the forest. There turned out to be some magical mold on the lemons, which when inhaled by Luna, caused a moldy lemon persona to form in Luna's mind. The persona was formed into the Vtuber Fermentangy.
