麥兜噹噹伴我心 (McDull: The Pork of Music) (Blu-ray release 2012-10-19) is the 4th cartoon movie in the McDull series, which is the most successful cartoon creation from Hong Kong. In this movie, the kindergarten has no money to pay the rent, so the headmaster forms a choir of kindergarten students, hoping to earn some money. As implied by the title, this movie is full of songs. Most of the songs are interesting in the conventional McDull style. Beneath the cartoon and the songs that can be appreciated by kids, the story is actually a sad satire of social problems of Hong Kong, such as the skyrocketing property prices.
