Horton Hears a Who!

Horton hears more than anyone believes.

An imaginative elephant named Horton hears a faint cry for help coming from a tiny speck of dust floating through the air. Horton suspects there may be life on that speck and despite a surrounding community, who thinks he has lost his mind, he is determined to save the tiny particle.
