On March 14 the movie Horton Hears a Who opens in theaters. Based on a Dr. Seuss book, the film stars the voices of Jim Carrey as Horton and Steve Carrell as the mayor of Whoville. It looks like a winner and there is already a cool website to go with the film. One of the things you can do on the website is adopt a Who. You get to pick a boy or a girl, give him or her a name and then dress and feed your little Who. My Who is named Jenny and she has pigtails. You even get a Whoville Adoption Certificate to print out.
