The Shiffle-Nosed Nergandingslinger are a species of colorful, yet rare, birds that make an appearance every ten years in Jollywood. One first appeared in "Free Teensy" at a carnival organized by Queen Delightful to raise money to preserve their nesting grounds. The birds later became the focus of the episode, "Uncle Humidor", when the titular character wants to document the bird in a drawing for his book, The Illustrated Companion of the Birds of Jollywood. So he, his niece Delightful, the 7D and Starchy travel to Mount Jollywood to draw them while the Nergandingslinger bathe in the waters at its base.
