What is That Thing That Comes Out of Zim's Mouth?

Guys, I watched this episode a hundred times and I am a little bit disturbed by that thing that Zim regurgitates out of his mouth in the cafeteria scene. Is it a crotch or something?

I haven't seen that episode in a while, but I think it's an intestine. Gato sin suerte 23:59, January 11, 2011 (UTC)
Yeh, I'm sure that's a Small Intestine. dB I pay too close attention in Science class. Pokemonic 22:13, June 7, 2012 (UTC)
