19 parts Complete This is how I imagine the series if it got another season that takes place directly after Enter the Florpus:
Gir glitches, Membrane keeps secrets, aliens live among us, secret societies are not to be trusted, Dib is going through a lot now.
I try to keep the tone of the show as far as the jokes go, but this is, with each chapter being an "episode," going to be a bit more serialized, it is my epic Invader Zim story I wish would make it to the big screen!
