Assuming your hostess is classy enough to have toilet paper, grab about six plies and fold so that you have three layers - each two plies long. Pinch in the middle to form a head. If you are fortunate enough to be trapped in the toilette of someone who has good dental hygiene, then you should be able to locate some dental floss. Break some off and tie around the paper to form a neck. You can then rip two strips along the sides and tie at the ends to simulate arms. If you have something against fat people and feel the need to give your doll a waist, you can also use floss to cinch the middle.
