I think Horton is KI material, and I'll explain why. Only not here. My re-telling of this Dr Seuss classic tale makes for long, tedious and cumbersome reading, not for the likes of these pages. If you are brave enough, refer to the following link: The KI of Horton.
BTW, the entry refers to the movie version of the story, not the original Dr Seuss book, which can be read as a social commentary -- as in, say, a parable of the increasing recognition of minority rights in the USA -- though it doesn't go as far as the movie in fleshing the characters and situation out.
