The colorful foursome from Down Under invites kids to sing along as they put 32 favorite nursery rhymes to music. The songs aren't just fun; they also encourage young viewers to learn rhyme, rhythm, sound, language and even some math. Traditional musical instruments are also on the bill, accompanying tunes such as "Jack Be Nimble," "Black Velvet Band," "Rub a Dub Dub," "Old King Cole," "I'm a Little Teapot" and "Polly Put the Kettle On."
