Horton the elephant comes to the rescue again in this video. Horton, with his sensitive hearing, is the only person who can hear the pleas for help from the microscopic world of the Whos, a world so tiny that it fits on a speck of dust. Horton's friends can't comprehend that there are living beings that small, but the Whos manage to make their cries heard just in time. Another Dr. Seuss classic is successfully adapted for the small screen. Recommended for all ages. ~ Heather M. Fierst, All Movie Guide
