haha, nice! Carnivorous Plants, like Treants, are those type of monster you can decide to kill them since they have a hight % item drop chance. But sometimes its risky!
I had a run where I was in an open space, with a lake, full of sleeping Treants. Moved one tile and triggered a firetrap. The fire spreds fast, waking up all the Treants and they managed to kill me in 2 turns. lol
