I couldn't finish 'em. Looks like this's gonna get complicated.
The Green Grass is an enemy in Crisis Core -Final Fantasy VII-.
Green Grass are not very powerful foes, but they can inflict Curse with their Firaga spells, as well as Silence with their Hysteric Voices ability. They are weak to Fire-elemental attacks, so abilities such as Hell Firaga or Tri-Fire will defeat them with ease.
