In Roald Dahl’s classic book ‘Charlie and the Chocolate Factory,’ there are exactly 100 Oompa Loompas. These small, orange-skinned, green-haired workers are originally from Loompaland and are brought to Willy Wonka’s chocolate factory to help with the production of candies and chocolates. They are known for their hard work, cheerful nature, and their tendency to break into song and dance whenever something goes wrong in the factory. The Oompa Loompas play a crucial role in the story, often providing moral lessons through their songs.
