Turns out Yakko’s in charge of the South Park crossover now. God help us all.
In the near future. Or so they say.

Sorry, but I don’t really see much logic in riffing a crossover upon its creator’s demand, no matter how much they have changed.
Crossover hell in its current status. They’re already plannning Winnie the Pooh Meets Moana, which will co-star:
the rest of the entire cast from South Park: Bigger, Longer and Uncut (excluding the Topless angels and the C******s, since they are not appropriate for a kids’ film)
