Oh my! Their deaths was/or gonna be soon enough... Caused by the selfish sibling's bacteria filled... You know how it goes.
Thinking of mouths... That reminds me of when i saw.. One of those movies at the theater. The moment we got to see those ugly looking big gremlins, piled at some dark setting, sweating and just looking foul while working. The smell of overly butterfied popcorn reached my nostrils, and i couldn't help but feel really really sick. And I'm a person who usually eats my dinner while watching Bones... Nice effect though, in a way. The evil sweaty monsters of LOTOR smell like popcorn, gives you a somewhat wrong impression.
