This poor cavegirl has stumbled into a deadly carnivorous plant. The lip of the plant, at ground level, is just out of reach for her, but it doesn't help that the walls of the plant's inner cavity are rubbery and slick either. Having fallen in, her weight upon the plant's spongy floor causes it to begin secreting a slow-acting digestive acid. Unfortunately for her, this acid will take several days to complete its work. If that wasn't bad enough, the plant only creates enough to fill its chamber to about three feet, so not only will she suffer the agony of a slow acid bath, but should she continue in her futile escape attempts, her ordeal will just last that much longer, as inch by inch she sinks deeper and the digestive juices wash over more and more of her. It would likely be a more merciful death if she drowned herself once the plant finished filling, but even then she would feel the searing pain of the acid burning at her from the inside out for some time.
