'Josephine is a kangaroo - who loves to dance ballet. Her little brother, Joey, tells
her that kangaroos don't dance, they hop - but Josephine continues to point her
toes and leap through the air.
When a ballet troupe comes to town and both the lead ballerina and understudy
are injured, Josephine's talents are called upon to help save the day. Can she do
it and, more importantly, does it matter that she's a kangaroo?' (Source: publisher's teachers' notes).
