Not sure if this is breaking the fourth wall, though. Even if these dolls (or pictures) are beginning to realize they are dolls (or pictures)… they still have no idea they’re in a comic, and certainly no idea that that comic is WITHIN ANOTHER COMIC.
If there is an anime called “Goddamn! All Purpose Cultural Catgirl Nuku Nuku DASH!!!” and another one called “Butt Attack Punisher Girl Gautaman,” I would not be surprised by one called “Tangler Gnome Mongrel Gnat.”
Perhaps this is why autistic kids get the Sally-Anne test wrong. Other kids are so cruel to them, they already know from experience that if you leave your stuff unattended, the most likely assumption is that someone will have stolen it by the time you return.
I suppose if you acted out the scenario with lidded boxes and baskets, AND a doll habitat complete with rooms separated by walls and doors, you might be able to convey the correct message. But it might still be hampered by the fact that you’re using dolls in the first place.
