The dungeon has been parasitized

Dungeons? Monsters? Demi-humans? And dragons? But I'm just a plant! Reincarnated as a blade of grass, without hands, feet, or eyes, how can I survive in a dangerous dungeon? The answer is—activate the skill: Parasitism! Seeds sprout roots, piercing flesh and blood, penetrating the soul, making everything its captive. Enslave monsters, kill monsters, and gain even more power. Go parasitize the entire dungeon! (This isn't random writing, nor is it based on assumptions; I received guidance from my potted plant at home.)
