Even as a kid I got scared teletubbies.. Even till this day. Same goes for barbies and mickey series, there's just something eerily disturbing about them for me atleast.
I would really like a bow over fairy tail, saving zeref and mavis from their curses, giving them a second chance which ankhseram has deprived them of. My favorite couple would like to see them highlighted or being helped by the almighty Grandpa!
