The Three Caballeros track Sheldgoose to Nazca, Peru, where they become drawings at the Nazca Lines. While their images remain on the surface they enter an underground society where everything looks drawn. The Caballeros believe Sheldgoose is after a mystic item, but learn it's a trick. His plan was to lure the them underground, so he could go back to the surface and erase their images and them. With Sheldgoose and Felldrake riding their flying minion Leopold, the Caballeros must draw their own vehicles of transportation to the surface. Jose's looks like a Renaissance painting, Panchito's a comic book, and Donald's a three-year-old's doodle. If they don't win the race, they'll be erased from existence!
