Well Pixtopia I don't really care for because they know it just Star and the gang trying to escape from the pixie mine and they don't even spend that much time on it in the promo. But Mewberty on the other hand is something i'm really hype for because if you notice something in the promo, Star is going after every boy in the school but not once she go after Marco. In fact he the last one so maybe he the only one that can fix this. So I can see a starco moment happen between them.
