I also need a source that says that Fred Gonzales also didn't start boarding with Squirrely Puffs. While everyone's scurrying for the source where this new Einstein got this info, I'll be waiting here for the source that says such things.
I don't see any information on that either... according to the episode titlecard, it was written by Fellows, Hartman, and Sullivan, storyboarded by Wincat, Hammersley, Hartman, and Marty Warner
