Probably suspense of disbelief, or whatever it is. That, and it’s a pretty meta things that would probably work best in a comedy cartoon.

I know the show Chowder had an episode where they “ran out of budget for the animation” and did a pretty short gag where it switched over to the VA’s and how they had to fundraise to get back to their animated forms. But I don’t know many other shows that could or even did that type of meta humor.
