Like the wolds worst waterslide, you slide down the pipes and open out into the sewer. You free yourself from the shit and paper. You are naked, tiny and cold. You start a trek through the sewers. You have to get out of hearing and possibly back to your mother, the only one who could turn you back.
About an hour in, you find a scrap of red fabric that has been flushed down here, it is not too soiled. You wrap it around yourself like a blanket. Later you find a sowing needle that is about 4cm long. To your 12cm size, this is a sword. You use it to hold the fabric together like a dress, your needle running along your side. You head out on your journey.
