Create a vibrant and colorful illustration inspired by the children's story of the Three Little Pigs, emphasizing the importance of choosing good building materials. Show the three little pigs building their houses side by side in an enchanting forest: the first using straw, with a rushed and careless expression; the second working with wood, showing some effort but lacking attention to detail; and the third building a sturdy stone house with a focused and determined expression. Add the Big Bad Wolf in the background, watching with a mischievous grin, ready to blow. Include details like flowers around, scattered construction tools, and a bright blue sky to catch children’s attention. Visually highlight the stone house as the strongest and most protected, contrasting it with the other two that appear fragile.
