Horton Hears A Who 4
Back in Whoville, at one point all seems lost, as the inhabitants of the spec of dust planet are making as much noise as they possibly can, to no avail. The threatening society of jungle animals still do not hear them, until a little girl sitting quietly, alone in her room.
She is quickly brought to the top of the tallest building in Whoville, where she lets out a small peep. This proves to be the straw on the camel’s back that makes the difference and allows the doubting animals to hear the tiny planet calling out in a plea for its very existence.
