Character. Gonzo is not a puppet version of a human or a recognizable animal. He has an awkward, non animal-like appearance, which includes purple-blue fur, purple feathers on his head, bug-eyes, and a long, hooked nose, referred to as a "beak".
Why is Gonzo in love with a chicken?
Even as far back as episode 217, Gonzo finds love with a chicken when he sings "Won't Somebody Dance with Me" at the dance. Gonzo loves Camilla, but sometimes he chases after other chickens, because he's not always sure which chicken is which.
Who is Janice the Muppet based on?
Her name is probably a reference to Janis Joplin. However, in her final form as built by Bonnie Erickson, she bears very little resemblance to either Jagger or Joplin.
