Alright, I got an idea: it's been six years after the latest land before time film. For almost twenty years, the gang has been doing sequels to keep the struggling Universal Cartoon Studios afloat. They remember the love and passion their creator had for 2D animation and, seeing the rise of companies like Pixar, wanted to save UAS from being closed down. After their long years of sequels, the joy they felt in doing the movies began to dim, but were still encouraged that they were doing a good thing by keeping so many 2d animators employed. When their twelve movie contract with universal expired, however, they realized that the contract that they had signed years ago had a loophole in it that nullified Universal's obligation to keep Universal Cartoon Studio's alive, and axed it as soon as the thirteenth sequel was finished. Furious that they've spent twenty years working for nothing and saddened that they failed to keep the studio alive as a tribute to their beloved creator, the gang quit the TV series they had done as a side project and went into retirement.
Six years later, the gang comes to an alarming discovery: they once again see an audience, something that only ever happens when they're being animated.
At first, they're too deep in the enjoyment of their retirement to care, figuring that who ever was animating them couldn't force them to have an adventure if they didn't want to. But then disasters start happening in their world. They are forced out of retirement and into an adventure.
I have ideas for the adventure too, but if all the other stuff isn't interesting, then neither will the adventure. I know it also isn't 100% accurate, but hey, anything for a good story, right? So what do you think?
