It would also be a nice, but completely irrelevant idea if you could save short scribbled notes in the rabbit hole via the touchscreen. For example, it could work like this: you could say to r1 “I want to draw something”, the screen would then turn into a post-it, you can draw someting nice and when you then say “save this”, it would be saved as an image in the rabbit hole. Done!
Of course, r1 should also ask what the child’s name is so that r1 can remember it later.
