Step Inside - Oonga Boonga

The magic house invites viewers to step inside and join Twinkle, Chloe and Boris for a story. Mr Mopple finds a harmonica in the garden shed. The harmonica reminds Boris of one of his stories, which is about baby Louise who won't stop crying, even when Grandpa plays a tune on his harmonica. Only her brother Daniel can stop her crying, by saying 'oonga boonga'. It doesn't work for the rest of the family, so does Louise simply stop crying when her brother holds her?
