Please create black and white images with clear, well-defined outlines suitable for coloring. The images should be thematic and engaging, including the following themes: Jungle Animals: A majestic lion, an elegant giraffe, and a playful monkey in a forest setting. Marine Scene: A colorful fish swimming among corals, a sea turtle, and starfish. City Scenes: A park with children playing, a bench surrounded by flowers, and buildings in the background. Nature Elements: A large tree with leaves, various flowers, and a bright sun. Outer Space: A rocket launching, planets in orbit, and stars. Festivities: A decorated Christmas tree, fireworks, and Halloween pumpkins. The images should be simple but detailed enough to be colored. Ensure that the lines are sharp and that there is no shading.
