Boys and girls everywhere, this story is about a young flea by the name of Paco, who belongs to a traveling flea circus currently touring the country. Paco accidentally meets Chico, a mixed-breed Chihuahua on the beach while sunbathing. Chico stumbles upon Paco as he walks along the beach. Tensions temporarily rise between the two, but when Chico apologizes, Paco realizes that Chico didn't step on him on purpose. Both Paco and Chico shake hands, and they soon become best friends. Paco will need Chico's friendship because Paco is an impulsive young flea who loves to explore his surroundings and tends to get into trouble if left unchecked. As the traveling circus tours the country, Chico's relationship with Paco will be greatly tested to see whether he can keep Paco out of trouble. Things will be touch and go.
