I started out shooting a mushroom and it fell over! Next came the hydrangea all by itself followed by a new hat for it! Then that app Pic, monkeyed around with it a bit and finally I said, that's enough!
In short Horton hears voices coming from the dust spec on the flower, so he starts talking to it...telling the Whos that he will care for them. The other animls think he is nuts and treat him as such, but in the end he is able to convince them that he is not crazy and they realize he was telling the truth all along. Funny characters and rhyme aside, Seuss was really making a commentary about our tretment of one another. :)
