When Mark takes care of an abandoned demon baby, Callie finds herself suffering from strange maternal demon impulses, and Twayne smells her pheromones and grows a mating bone.
Take New York City, add every horrifying beast, science-fiction freak and fantasy faerie, shake thoroughly and you've got "Ugly Americans". The animated series follows Mark Lilly, a social worker at the Department of Immigration, as he helps new citizens both human and "other" adapt to hectic life in the Big Apple.
There are easier tasks than weaning vampires from blood, socializing land-whales and housebreaking werewolves, but Mark is up to the challenge. Between his stressful job, a zombie roommate and a demon girlfriend, Mark's lucky if he can sneak in a few minutes of sleep. But who can sleep when there's a drop-dead gorgeous mermaid sitting at the bar?
