In Horton Hears a Who! we meet Horton, a kind-hearted elephant who lives in the Jungle of Nool.
Always open to the world around him, Horton hears the tiny voices of the microscopic Whos and promises to look after them.
This proves to be quite a challenge, but Horton and the Whos work together to make themselves heard.
Horton Hears a Who! is based on the picture book classic written by Dr Seuss and published in 1954.
