When the Lion Guard hears a cry for help, Ono sees a serval struggling to keep from falling into Big Ravine. Fuli races to the rescue and jumps across the canyon, nearly falling in herself. She gives the serval a boost from behind, and he thanks her for rescuing him.
A leopard named Makucha is running away from the Lion Guard when he happens upon Big Ravine. He leaps the ravine in a single bound, and the Lion Guard skids to a halt on the other side. Laughing, Makucha escapes.
