Erhm.... I don't think small chubbie creatures with large eyes dressed in extremely skimpy clothing (Face it, they are.) defines 'cute'. 'Disturbing' is a better word. We all remember the 'Liscensing magazine.' shots of Lockette, but more so Chatta and *Shudder* Amore.
*WARNING! Despite this being Winx, I think this is inapropriate for younger viewers. Seriously, Straffi, what the hell?*
*Points at infamous Pixie Pictures* Cute....? Not really..... If they ever appear on TV like that, I'm giving Winx a 'Getting stuff past the Radar'-entry at TV-Tropes.
