In the meantime, the jungle's resident busybody Kangaroo (Carol Burnett) is hopping mad over what she perceives as Horton's unacceptable eccentricity, which she believes will "poison" the minds of "the children." After all, she says, "the jungle's no place to act like a wild animal." Kangaroo sets out to prove Whoville can't exist by destroying it (typical busybody logic), hiring a bloodthirsty vulture (Will Arnett, TV's "Arrested Development" ) to act as hit-bird.
Visually seamless and voiced with restrained frenzy by Carrey, Carell, Burnett, Seth Rogan, Jonah Hill, Jaime Pressley, Amy Poelher, Isla Fisher and others, "Horton" manages to stay on its narrative track rather than getting bogged down in its own silliness, which would have been very easy to do. A good time for kids and adults alike. G
