https://www.youtube.com/watch?v=MrcP3U8HlHM (We see Zim thinking about something as GIR stares at him.)
GIR: Hey Zim what are you doing? MMMMMMMMMMMMMMMMMMM paint chips
Zim: I'm trying to figure out something, that cat you and I saw yesterday, there's something very odd about it like I’ve seen that thing before.
GIR: Maybe it was a movie or something.
Zim: No I saw that thing with my own eyes about 11 years ago.
GIR: Was it a friend.
Zim: No wait a minute.......................
GIR: Is it the ruler of some far off world.
Zim: GIR where do you think that thing is hiding?
GIR: I don't know.
https://www.youtube.com/watch?v=j2KHXyw0hc4 Zim: I think that they might be hiding at a abandoned factor that produced wieners.
GIR: When We get there Can I eat some?
Zim: Sure, but they probably expired.
GIR: OH.
Abandoned Factory, inside, day
https://www.youtube.com/watch?v=6uZq6ntDvC8 GIR: It sure is dark in here Zim.
Zim: You want to know something I noticed.
GIR: What is it?
Zim: There has never been a single horror film that takes place in an abandoned factory, they always just happen to take place in other abandoned buildings.
GIR: Why did this place close?
Zim: Well GIR, it closed down when the workers couldn't find the owner or his daughter after an earth quake.
GIR: Wow.
https://www.youtube.com/watch?v=eyYSZNoi5TI Zim: Speaking of which this pretty advanced technology for a place like this, isn't this place just suppose to make only hot dogs?
GIR: I think it might have alien stuff in here.
Zim: You could be right-

Zim: GIR!!! GIVE HIM BACK YOU CREEP!!!
(The silhouette darts away as Zim just dodges the traps set before him.)
Zim: How feeble, How Childish. Is this the best you honestly got?
(Suddenly a platform that Zim was standing on starts to move on it's own above a huge bottomless pit)
Zim: I spoke too soon.
(Zim manages to jump across a ledge and scramble up before the platform falls to the ground.)
Zim: That was too close for comfort now I got to find GIR-
https://www.youtube.com/watch?v=ydL4TrO-51A (Zim turns to see a cat standing behind him. She looks like this)

Zim: W-what the?!
(The Cat glares at Zim and scurries off Zim follows the cat form sometime until it leads him to GIR wrapped up in some string.)
GIR: Hi Zim!
Zim: GIR who did this to you?
GIR: The person standing behind you.
