Jett's delivery today is going to Catalina in Alqi Valley in Chile. She wants to visit her pen pal Ro from Mars and give her a small stuffed Andean fox. With the help of the Super Wings, Catalina and her father go on a big mission to Mars. When they get to the top, Catalina learns that her father just made up Ro. But Catalina soon comes across a rover that was left behind and begins a new pen pal friendship.
