Gaz, Taster of Pork
"Gaz, Taster of Pork" is a double-length episode of Invader Zim, originally produced as Episode 26 and based off of a "MEANWHILE" featured in the back of "SQUEE'S Wonderful Big Giant Book of Unspeakable Horrors," another work of Vasquez. [citation needed] While not airing on Nickelodeon in the US, it aired on the Nicktoons Network in the US on August 12, 2006, and on YTV in Canada on March 2 2007. This is the seventh double-length episode of Invader Zim. Jeffrey Jones voices a deranged hobo and the Shadowhog.
Plot
Dib has acquired a "spell-drive" (hinting that Invader Zim is in the future, where books are obsolete), an anthology of various spells in a kind of digital book. Dib thinks that it is no longer usable, but learns that he can try out a spell. Dib tests a spell from the "Shadowhog" on Gaz, who is sleeping in the next room.
The next morning, Gaz doesn't seem to be any different, but it turns out that the spell did work. Gaz discovers that she tastes nothing but pork in everything she eats, even dairy products (although she finds that actual pork tastes the same). Dib desperately works to save her from her fate, even calling on Zim (though it doesn't work out). Gaz becomes a media sensation, and a movie is even made about her (which GIR and Pig go see).
Finally, Dib transports he and Gaz to the Shadowhog's dimension with a new spell. The Shadowhog turns out to be a tall, large magical being with a pig head. He declares that to reverse the spell (which is a wonderful spell in their dimension), Gaz must face him down in a challenge. Dib is forced to wait outside, convinced that Gaz won't be able to win.
As it turns out, the questions are very easy (as Gaz is a video game addict) and they mostly play chess for awhile, as Gaz explains her knowledge of Zim's identity (she knows, but realizes that he is too utterly stupid to conquer the Earth).
