Lucky Australian Winx fans, Winx Club is showing on 10th September at 11 o'clock! Don't forget to see it on Nickelodeon! You can also buy the Magical Adventure in Italian here! Here are some Winx merchandise which I believe... is Season 5 clothes! Thanks to German Winx for the pics!
You can see that they are all wearing rock music clothes. So here's my guess for Season 5: Remember the Winx band in Season 4? Yep, I bet they became professionists or something and they are worldwide famous!
