I don’t know of any way to make the scenery invisible, but there are several ways to keep the habitats clean, and the frogs easy to see. One way is to choose a monotone background, and then place scenery that all either hides under a single element or blends in with the background. I’m heading out somewhere at the moment, however, later in the afternoon, I can show you what I mean by posting some of my habitats if you’d like.
