Dugan

The Nocturnal Petting Zoo is a scheme cooked up by Roger in "Stan's Food Restaurant". When Francine and Stan have a bad meal at a restaurant, they see Roger with a display of animals in a shopping center parking lot. Roger is forced to repeatedly fend off Dugan, a vagrant who is drawn to Roger's Nocturnal Petting Zoo. Roger is forced to chase him off by spraying him allegedly with urine.
