Disney's Little Einsteins: Mission Celebration

My brother was obsessed this show. He still sings classical music today. Kids will learn about music, geography, animals, and art. However, this show is ANNOYING. It drove my family NUTS! The characters have irritating voices and speak haltingly. And I don't understand why the rocket can't speak English... I mean, if the rocket had to talk, why not let the watchers understand too?
