A vibrant cartoon with colours and smooth animation. Imagine you tell the AI: "Create a colourful 3D children's cartoon. A cute 4-year-old Nigerian girl named Mimi has two afro-puff hairstyles and wears a yellow dress. She is in her bedroom playing with her teddy bear. Her little brother walks in and asks to play. Mimi refuses and they argue. Make the characters cute, expressive and suitable for children ages 3-6."
