Yeah. Definitely a park vehicle, painted as such.

What's "happening?" I'm still trying to figure out what Cartman or South Park has to do with anything in the picture.
That "I Never Should've Gone Zip-Lining" episode happened to air when there was a national (international?) news incident involving a pretty girl who contracted flesh eating bacteria while zip-lining and was in a coma and getting amputations after a seemingly minor cut. It seemed strangely relevant in a "It's happening!" way the same day it aired.
