Cartoons! ..That never made it.

I am considering doing a regular series about pilot episodes of shows that never got picked up, and perhaps pilot episodes of shows we are familiar with, but wherein the pilot differed greatly from the resulting show. This concept of course brought to mind the old interstitial shorts on Cartoon Network (back when CN was still good) “Cartoons That Never Made It”, with the obvious difference being that the “Cartoons That Never Made It” “pilots” were never intended to be anything more than a joke. The “Salt & Slug” song and the “Heidi & the Yodellers” one still stick in my head to this very day.
