I really wonder how do people see "so many plot holes"? Because I can see ONLY TWO and even they are relative.
A plot hole is something that causes the plot или a part of the plot to not add up или to not make sense. These two Фильмы don't have such, as all Ты have to do is pay attention to what is сказал(-а) and how it is said, and at some points to use common sense.
1.) The cub's Дизайн and the ceremony.
But officially that is not a plot hole. As Дисней has made it official it is "Fluffy"/Kiara in the movie universe. As in introduced no one else in the Фильмы - basically we just have to accept that...
