Horton finds a speck, and knows that someone is living on it. He knows because he talked to the mayer that lives on the speck. The place on the speck is called WhoVille. The mayer tells Horton that Horton needs to find a salama place for the speck au the speck will be destroyed.

So Horton Is traveling up a kilima to a salama place for the speck. But the sour, wamekula kangaroo, kangaruu doesn't want Horton "rotting the childerens brains". she wants that speck destroyed. so she sent a bird to go get the speck, and have it destroyed. So when horton is almost there the bird comes and drops the clover/speck in with millions of other clovers.

horton startes looking right away, but with millions of clovers its almost impossiable. then when he is about to give up he finds it. But then,again, the clover gets taken, and is about to get boiled because of the sour, wamekula kangaroo. but then the people of whoville make lots of nosie so the sour, wamekula kangaroo, kangaruu can hear them. then they are saved and they can live happily over after.
