Horton Hears A Who(2008)
Based on the children's book of the same name. Horton is the nature teacher in the jungle of Nool who hears a tiny voice coming from a speck of dust as it flies past him. He later finds that the speck contains an entire town, the town of Whoville, and becomes friends with the town's mayor, Ned McDodd, who tells him the town is in danger unless he can find a safer place for it. Horton is very shy and refuses to tell his friends about the town inside the speck, which leads his friends into believing he is crazy and try all they can to rid the speck and kill him. Meanwhile, Mayor McDodd has a situation of his own, his teenage son JoJo is next in line to be mayor but he is too shy and soft-spoken for the job.
