I thought I'd post this, since I haven't seen it yet.
If you aren't a fan of the Nickelodeon take on Winx Club, you can watch the 4Kids dub instead if you have Sky, on the channel 'Pop'. I believe it is also sometimes shown on it's sister channel 'Pop Girl'.
Please note it only shows Season's 1-3, since 4Kids didn't do Season 4. It is currently airing Season 3, however, it goes in a cycle so when this ends, I'm presuming Season 1 will start again.
Just incase anyone wanted to watch the 4Kids version either out of preference, or to simply compare both!
