Step 1 : Introduction to the question "Who do the Italians call Topolino?"
...Mickey Mouse is known as Topolino in Italy. He appears in an iconic comic book of the same name, which has been published for over 80 years. In Italy, Topolino is one of Italy’s longest-running and best-loved comic books for kids. It all began back in 1932, four years after Walt Disney himself began drawing his Steamboat Willie cartoons. Italian editor Mario Nerbini began printing Mickey cartoons of his own, drawing a character called Topolino, which translates to “little mouse” in Italian. On the official Disney.it website, Italians can sign up for the "Topolino Club," which is the Italian version of the Mickey Mouse club. Topolino merchandise can be purchased in the Italy section of Epcot.
