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