Can also connect this point my earlier points that he never gives up. He encourages himself to find the small speck that fell into a lot of different speck field even though he couldn't find it for days.

Tries to protect the speck no matter what. One example: When the kangaroo tried to take the speck away from him at the beginning of the film, he didn't just give it away to the kangaroo. He kept it and this can also connect to my point that he is a very determined character because he is very determined to protect the speck.

We can't really see Horton being said in the film. Even though he has a lot of people who are against his idea such as the kangaroo, he wasn't sad but he became more determined to protect the small speck

"A person's a person no matter how small" This shows that he is protective because he can't even see it physically. Unlike other people, Horton believes that a person lives on that speck and that it is his responsibility to save those people and protect them from danger. He even put himself in danger when he was saving the speck. He also took a lot of risks to save the small speck. For instance, he had to cross a bridge that couldn;t hold his weight to save the small speck. This shows that he can do whatever he has to, to save the speck.

He never puts the speck away from him and was very responsible of it the whole time.
