The language of sheep is Baa and every single word is baa . . . There are many different ways to baa, but when they are lambs, sheep only know one kind, which is why the field trip Mrs Ramsbottom takes them on is so important. Mrs Ramsbottom takes her class out into the country to learn the finer points of baa in situ. And soon they're good enough to take their Baa exams, for which they all gain a gold star!
