Grumpy Nun: "My baby, not your baby!" Smug Nun: "In what sense exactly?"
Bunny Nun: "Why did you eat that Burger? What can I do?" Hungry Nun: "More... Food... Please..."
Idea Duck: "Yes, this is the solution. I got it from the stories of King Solomon in the Bible." Skeptical Duck: "I think you didn't got the point of that story."
Star Network Ducks: "We will help Hungry! Also stop hoarding the baby for yourself, Grumpy!"

Probably because their PCs have too many details to make them recognizable at first glance, whereas NPCs can be blander, and let "natural beauty" shine through.
