Good Little Monkeys is an MGM Happy Harmonies cartoon.
The cartoon starts in a rainy setting. We then find a book saying "Inferno Dante" as one page gets on fire from a little devil. He runs over to a skeleton head. We then see 3 monkeys singing. The little devil gets out of the skeleton head as he rings a gong bell. The 3 monkeys sing again. Other people sing as well. The 3 monkeys swing down a rail onto the floor as the little devil throws peanuts. The 3 monkeys eat some of the peanuts. Everyone else messes up. The little devil somehow leaves and jumps back inside the book as everybody else cheers. We then see the 3 little monkeys going back to their home spot. They sing again as the cartoon ends.
