Via
Web Curios, we are referred to this rather incredible resource from
Joi Massat that has compiled dozens of series pitches and show bibles for cartoons including
Dungeons & Dragons,
He Man and She-Ra, Spongebob,
Ren & Stimpy and many other classic Nicktoons.

Linked documents include character specifications, episode samples, lore and backstories and as a whole presents a pretty good guide on how to go about packaging and promoting one’s own animated ideas with a nice
supplement that outlines the presentation and pick-up process, selling the premise and refining their stories.
