Madagascar

Parents need to know that there's some crude humor and sexual innuendo that will probably go over the youngest kids' head. The animals confront assorted dangerous situations, including an encounter with police, containment in crates (dark, closed spaces), a stormy sea and shipwreck, and, most alarmingly, a startling personality change in Alex, the lion, when he wants to eat his friends. There's a shooting with tranquilizer darts in which a character hallucinates to the tune of Sammy Davis Jr.'s song "Candyman" (younger viewers won't know this is about drugs, but the allusion is there). Gloria the hippo briefly appears with seaweed on her body, simulating "pasties" on breasts and crotch area. The lemurs are hunted by scary hyena-like creatures. A secondary plot has a crew of penguins acting like spies, which has them tunneling out of the zoo, knocking out a ship's captain, and stealing an ocean liner.
