If you like pinball and South Park then you should probably be excited about South Park: Pinball. It's out right now as a standalone purchase, or as an IAP from inside Zen Pinball.
The game consists of two pinball tables. One themed around South Park in general, the other focussing on Butters. I don't really know who that is, but I typed it anyway in case you do.
As you might expect from Zen, it's a ridiculously polished adaptation, full of sound-bites, swingy around things, and shiny balls.
