AU dib(in stray jacket)

in this universe, instead of Zim coming to earth it was a Alien(Alien bumped off zim before he could get there, sorry zim better luck next time...if he somehow gets one). and still....everyone sees it as normal, though they beleive Alien is just a ugly dog, even though it proves many times its not.
dib, like with zim, tries to prove that the Alien is an alien from outerspace. even Prof. membrane believes Alien is just a dog(which it so obviously is NOT)...so much for being smartest man <-<
