[TOMT][MOVIE][2000s] cartoon about a jungle near a lab where the black panther/jaguar sacrifices himself
it is so hard for me to remember anything from this so please help me out!
There was this jungle near a facility or lab looking place and there were lots of animals inside the jungle. I think the lab was trying to protect the jungle. In a scene through out the movie the two main kids were playing by a river (body of water) with a huge tree branch, and I think two monkeys or birds joined them to play. Near the ending of the movie, something happens to the jungle that its collapsing. The black panther/jaguar that’s originally known as the “mean guy” helps everyone go thru a door (that looks like a garage door) but he gets left behind trying to save others and dies in the collapsing jungle, while everyone is the lab’s safe room that looks like a tunnel. That’s all I remember. This cartoon was also translated in Farsi.
