Madagascar is a children's animated film. It centers around a lion, a zebra, a hippopotamus, and a giraffe. The film starts off with the main characters living in a New York Zoo. They are unexpectedly shipped to Africa but along the way are shipwrecked in Madagascar. In this first movie, the lion is forcing his hunting instincts away and they are all wishing they were back at the zoo. In the second movie, while trying to leave Madagascar, they crash in Africa. There they meet more of their kind and the film ends with them living happily in Africa. All seems fine until the the third movie comes along. Here, they end up in Monte Carlo searching for the penguins in order to persuade them to leave for New York. However, their plans are interrupted by animal control who is trying to catch them. This begins a chase leading the animals to a traveling circus who take them in. By the end they realize they don't want to be trapped in cages at the zoo... but rather be in the circus.
This seems like such an innocent children's movie, but the message it's sending out is the complete opposite of what we are trying to unlearn. The animals are being depicted of actually being happy while captive in zoos and performing tricks for the entertainment of humans.
