The Dink Network

Funny. I started this thread out of curiosity, and now I actually need headless ducks running around. I mean, ducks that are headless to begin with, that run around the screen and give everything a nice red shade. Of course it'd be easy to make a loop that makes the beheaded duck splurt blood everywhere every now and then, but I'd like to use the same values that are used in "the real thing". (sorry for not being able to say things clearly right now, I'm terribly tired)

so, the question is, how do I activate the run'n'splurt "script" (I don't know what else to call it. "It?") without cutting off the duck's head?
