This set features three floating ducks with interchangeable faces expressing happy, sleepy, and surprised emotions to support emotional recognition. Their rotating propeller creates a 360° water spray, reducing bath time by 30% in toddler trials. Equipped with a water-activated motor that requires no batteries, the IPX8 waterproof design ensures safe use. The gentle 0.5W water flow and BPA-free silicone beaks comply with EN71 and ASTM F963 standards. Color-changing LED lights and textured wings stimulate visual and tactile senses, while detachable ducks aid in counting and color sorting, following Montessori bath play principles. The self-righting boat base with suction cups prevents tipping, and ultra-soft edges certified by Brazil INMETRO provide durability and safety in hot water up to 50℃ (122℉).
