Other mistake: When Viper slides the swords to Jackie and they come to a rest next to him, there is a small paper spider right beside Jackie. The only paper spider in the room, however, is Origami himself, and he is actually too far away at that moment and too big to fit the bill. Guess some of the animators got their depth perception messed up.

Trivia: For those who are wondering what a black panther is doing in a Mexican temple - this is actually a black jaguar. Its fur is rendered black by what is called melanism, an increased amount of black pigments in its fur. These black jaguars are rare, but they do exist.
