Create a vibrant and colorful illustration divided into three panels, each featuring one of the pigs dressed appropriately for the house they built. In the first panel, show the first pig wearing a simple, casual outfit, building a house of straw with a rushed and careless expression. In the second panel, depict the second pig wearing a slightly more protective outfit, working with wood, looking more focused but still not careful enough. In the third panel, show the third pig, wearing sturdy work clothes, building a solid stone house with a focused and determined expression. The Big Bad Wolf only appears in the third panel, standing outside the stone house, huffing and puffing in an attempt to blow it down. The first two houses (straw and wood) are not shown with the wolf, as they have already been blown down. Include bright colors, scattered construction tools, and a cheerful sky to make the scene appealing to children.
