It Feeds on Noodles is an unfinished episode of Invader Zim.
SPOILER WARNING OF DOOM:This section or article may contain spoilers!
In this unmade episode, Zim would've been mysteriously transformed into a vampire, much like the vampire paramedics who whisked Moofy away for one frame, in the episode "The Girl Who Cried Gnome". When he was trying to eat Chinese food at a restaurant in town (see "Zim Eats Waffles" for how he develops an immunity to Earth food), Zim would have become a vampire who must feed on noodles (as opposed to blood) in order to survive. Though it's probably safe to assume that the episode would be spent with Zim trying to turn back to normal, details are unknown since neither the script or audio were ever finished and/or released.

Facts of Doom
This episode would most likely have been a filler episode.
This episode also continues the info gathered from "Zim Eats Waffles", in that he's eating Earth foods with no ill-effects on him whatsoever.
