Donald is a smart promotion expert for soap. His soap factory is a smashing success, causing the sales of Scrooge’s soap plant to drop rapidly. However, Donald’s advertising campaigns are getting more and more expensive and his soap pieces are getting smaller and smaller. The new sultan of soap is on the verge of bankruptcy. So he is glad when Scrooge takes over his soap factory. Donald even finds a job in his uncle’s marketing department – doing street advertising for soap.
