Walk of Doom

When Zim gets annoyed by Gir’s inept nature for the last time, he finally gets around to upgrading Gir’s guidance technology and he wishes to test its capability. Initial tests look good so Zim wants to take Gir into the city to test and see if Gir can get them safely back to their headquarters. However, when Gir forgets to bring the new guidance chip with him, Zim and Gir must find a way to get back home, despite the fact that they have very little understanding of the way the city functions.
