Now that would be a fitting way to play an elf. Reminds of one time in DF modding, when I played an elf hunting down a rampaging treent. Moral of the story: giving a megabeast the [NATURAL] token will not make it peaceful towards elves.
Ooh, this gives me an on-topic idea. Ents. That disguise themselves as perfectly normal trees, up until you try to smash them, cut them down, harvest from them, or light them on fire. Doing any of the same to nearby trees might also set it off.
Attempting to build a pine lean-to from a pine treent will likely result in being assaulted by a nude, pissed-off, animated tree. o3o
