Yes, Tune and Digit really gone in Winx Club Season 6 and were replaced 由 Cherie and Caramel. (I actually hate when this happens.) So why were Tune and Digit gone and replaced 由 Cherie and 焦糖 in Winx Club Season 6? I think I know why. I think the reason why Tune and Digit left and were replaced 由 Cherie and 焦糖 was because of PopPixie. Because in PopPixie, Tune and Digit were not very 流行的 but Cherie and 焦糖 were very 流行的 and I guess that's why Tune and Digit are gone. And also, Digit in PopPixie was a boy, not a girl, like in Winx Club. I guess that's why Tune and Digit are gone and replaced with Cherie and Caramel. (Maybe really this is the reason.) And yes, it would be really ridiculous for Digit to come back in male because she was a girl. But I think it's ridiculous that Digit is a boy in PopPixie because she's a girl, not a boy. But still, it was ridiculous that Tune and Digit left in Winx Club Season 6 and were replaced 由 Cherie and Caramel. Anyway, at least there will be a 9. season of Winx Club, maybe the old Pixies Tune and Digit will return. I want them back, really! I hope Tune and Digit will return. If they don't come back and Cherie and 焦糖 come again, I will hate them and I will never 爱情 them again! I 爱情 PopPixie but couldn't they keep Cherie and 焦糖 just on PopPixie? Tune and Digit needs to come back urgently, really! Don't 你 think I'm telling the truth? Ain't I'm correct?
