The Pet Toy Expanding is a vibrant, interactive toy designed for pets in The Sims 4, featuring a colorful, bouncy material that expands upon interaction. Its base form is a small, compact sphere with a smooth, glossy surface, adorned with playful patterns and bright, contrasting colors. When activated, it unfolds into a larger, more complex shape with multiple layers and textures, including soft, fabric-like areas and rubbery, grooved sections for varied pet engagement.
