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 또는 a part of the plot to not add up 또는 to not make sense. These two 영화 don't have such, as all 당신 have to do is pay attention to what is said and how it is said, and at some points to use common sense.
1.) The cub's 디자인 and the ceremony.
But officially that is not a plot hole. As 디즈니 has made it official it is "Fluffy"/Kiara in the movie universe. As in introduced no one else in the 영화 - basically we just have to accept that...
