Dr Seuss Horton hears a Who!

The story is about a friendly elephant who strives to save Who-ville, a miniature world living on a speck.
Horton is a happy-go-lucky kind elephant, who teaches the kids about different things. One day, while teaching, he hears a 'who' while a speck floats around and concludes that there must be a small world on the speck. He carefully maintains the speck on a clover and confirms his suspicions when he hears Mayor Ned of Who-ville speaking to him.
Ned is overwhelmed, but finds out that any effect on the speck could be catastrophic and asks Horton to find a safe place for the speck. Horton discovers such a place and starts travelling there. Meanwhile Kangaroo, who has an unpleasant and strict disposition, finds Horton disruptive and discourages Horton. Horton refuses to give in, which angers her and she finds Vlad, an eagle to destroy the clover.
Ned, on the other hand, tries to convince the inhabitants of Who-ville about the issue, but finds no support. When Horton sleeps with the speck nearby, it ends up snowing in Who-ville. Vlad finds Horton and drops the clover into a huge clover field, which impacts Who-ville like an earthquake.
After going through 1 less than 3 million clovers, Horton finds the speck again and the Whos believe Ned after the catastrophe. Kangaroo discovers Horton still has the clover and instigates the rest of the animals in the forest against Horton. They find him and cage him and are just about to destroy the clover when Kangaroo's baby hears the Whos making a din on the speck and all ends happy.
I expected the story to be funnier and it was a disappointment. However, the story line had an interesting theme with multiple universes and people on all levels. A tolerable story.
