Pedro is the main protagonist of the segment with the same name who wishes to be like his father who carries the mail between Chile and Argentina. Pedro goes to school to study aviation, including geography about the mail route between Santiago and Mendoza just like what his father did. Since Pedro's parents cannot do the mail route, he takes off to Mendoza where his first task was to pick up the mail at Mendoza. Pedro then arrives at the Upsallata Pass where he flies perfectly until he sees Aconcagua, the highest mountain that Pedro must avoid in his path.
Going past Aconcagua, Pedro suddenly arrives in Mendoza, Argentina where he picks up the mail. He suddenly feels overjoyed that his parents would be proud of him for completing the task. Pedro follows a nearby condor back to Aconcagua as he forgot his responsibilities of what his parents told him like avoiding downdafts and Aconcagua. Pedro then encounters Aconcagua again and is suddenly afraid of the mountain and the storms. Pedro is then caught between a heavy rainstorm, losing vision on his way back to the airport, making it more challenging for him to return to the airport. Pedro suddenly runs out of gas and is lost in the heavy storm. After Pedro's parents believe their son is gone, Pedro is revealed to have survived the storm and arrives back to the airport in Santiago, Chile, carrying the mail safely only to find out that the mail is actually a postcard, making his parents proud and completing the task as Pedro feels satisfied of himself for finishing the task.
He makes several cameo appearances as a guest in House of Mouse. In Mickey and Minnie's Big Vacation, Pedro was seen getting Mickey on stage. In Donald Wants to Fly, Pedro was seen again entering the House of Mouse and sees Donald flying above him.
- When Chilean comic artist Pepo saw Pedro for the first time, he didn't feel that he represented the Chilean culture, which inmediately became an inspiration to create his most famous Latin American comic book series, Condorito.
