OOLY's dog hidden pattern coloring set adds a surprise element to standard coloring. Kids can fill in 12 adorable puppy illustrations with markers and watch hidden patterns emerge within the design as they color. The reveal moment keeps kids engaged and coming back to finish each page, giving this set stronger play value than a standard coloring book. Compact and travel-ready, it's a natural grab for road trips and restaurants, and pairs perfectly with OOLY markers like Big Bright Brush or Color Together for shops looking to merchandise a ready-made bundle.
