Big and Small - Series 1 - A Sound Idea

The adventures of two unlikely friends. Big and Small hear a strange sound one night. When they investigate, the discover it is Ruby practising a new song she has written about how lovely the Moon is that night. Big thinks the song should be softer and invents a Twanger to help out Ruby. But Small thinks it is too soft and that the song should be as loud as a trolley of ribbiting frogs. Ruby declares enough is enough. It is her song and do Big and Small want to help her or do they really want to do their own thing? So Big and Small join with Ruby to sing her song, her way, and they agree it is not too loud and not too soft, and sounds very good.
