Big-Lipped Alligator Moment: The scene mentioned under Foe Yay is specifically stated by the author to be there only to please the ZADR fans. It is never mentioned again, and in fact, the following chapter has a flashback showing what really happened, which has no Foe Yay at all.
In fact, that chapter could almost be considered a Bizarro Episode. It does get mentioned briefly the following chapter, but aside from that, it just completely comes out of nowhere, and the plot seems closer to a canon episode, whereas most chapters leading up to it had been increasingly more serious.
Foe Yay: There’s a “happy ending” scene at the end of “The Terror of the Pies” when Zim and Dib just finally break down the walls, finally satisfying all the fans who were waiting for a ZADR moment.
