 " Pinkeye " was the first South Park episode to feature a cold open , or an opening scene jumping right into the story before the opening credits are shown . In all previous episodes , and the majority of those following it , the episode starts after the opening credits and follows a three @-@ act model , more in the style of a short film than a traditional television episode . " Pinkeye " was the first episode in which Kenny 's death was a key element of the episode and a catalyst of the plot , rather than a throwaway gag . It was also the first time Kenny died multiple times : once in the beginning , once as a zombie and once at the end when he is resurrected a second time . The blood featured in the episode was deliberately designed to look primitive as a reference to The Spirit of Christmas , the 1995 animated short film by Parker and Stone that served as a precursor to South Park , in which the blood was literally drawn with a Sharpie marker . For the final scene when Kenny comes back to life a second time , the dramatic music was inserted at the last moment by Parker with a synthesizer .
