Sanjay

Sanjay is considered one of Timmy Turner's so called back up friends, the other being Elmer. Obviously, by the wording back up friends, it's clear that Timmy is not as close to him as he is to Chester McBadbat or A.J.. In fact, Sanjay once stated in an episode that he'd never been to Timmy's house while both Chester and A.J. have been there several times. That said, Timmy and Sanjay do seem to value each other's friendship. He had even less of a presence in the sixth season than even Chester or A.J. He only appeared in Wishology Part I: The Big Beginning in a cameo.
