Horton is a is a kind, sweet-natured elephant who cares about other animals or people. Though he goes through many hardships, whether trying to keep an egg warm through storms, rough travels, and humiliating shows, or tries to save a small planet from harm, he always triumphs and the egg hatches into an elephant-bird, while the planet is saved and respected by the others. Horton is very popular because of his big heart and respectful compassion, which makes him more humorous.
He made an appearence in the books Horton Hatches the Egg and Horton Hears a Who!, both by Dr. Seuss.
Horton is voiced by Jim Carrey in the 2008 computer-animated adaptation of Horton Hears A Who!, where he appears as being eccentric and imaginative, as well as sort of absent-minded.
Horton will make his guest appearence in the Ice Age crossover Manny, Sid, and Diego's Adventures of The Jungle Book, where he would join the Sub-Zero Adventure Group at the end.
