Can you hear it? No? You can't. Isabelle and her dolphin from the Schleich® BAYALA® collection can hear it. Like every dolphin, this one can make very high-pitched sounds called ultrasound. When the ultrasound waves hit an object underwater, they bounce off as an echo. The dolphin and Isabelle use echoes to navigate the depths of the Atlantic Ocean or the clutter in your desk drawer. Pretty clever, right? That way they always find their way to you. And it's also a secret language. But they have no secrets from you. Maybe except which one of them is the fastest swimmer. Who do you think it is? Dimensions: 18 x 15.1 x 7.9 cm Age: 3+
