Watching cartoons is a great way to improve your understanding of spoken Italian. When you’re a beginner, listening to Italian at length can be very tiring. This cartoon is very short and you should be able to watch the whole thing easily even if you are a beginner. Beyond that, the characters speak with a variety of exaggerated accents, which will help you develop your ear for spoken Italian.
Personally, my favorite coso is Loco, because, like me, he still has some trouble speaking Italian! He’s also very cute. See?
