Today Kit and Pup are exploring the opposites Rough and Smooth. They start by roller-skating in the park. Kit is skating on the smooth path, but Pup is having difficulties skating on the rough, bumpy path. Kit and Pup then try to find as many rough and smooth surfaces as they can. In the live-action investigation Kit and Pup help the little investigators sort rough and smooth objects. And in the stop-motion moment a rough avocado transforms into a smooth pear.
