Weasel,
Have you seen a walrus' male appendage? Saw one on a move once. They are pretty big and I think that you could get one hell of a howler out of one, or about 10 for that matter look it up. Yellowhammer says 24"-30" long. That is a weapon of mass reproduction, not mass destruction, ha ha. I can't believe I even made it to the end of this thread.
