Need wandering vendors

Would like to be able to hire some vendors to wander the park selling souvenirs and stuff. Could even hit queue lines where guests are trapped in a no-spending environment. Let's help them spend every penny!

[woah] I just had a vision of a park mascot with a T-shirt cannon popping out a complementary T-shirt now and then. [woah]

Have a guy with a giant pole of pretzels waltzing along the paths, calling out to come get your freshly baked, giant soft pretzels. Anytime someone comes up to buy, he tips down the pole and they jump up to grab one.
This would be really awesome to see animated!
