Billy jumps in shock as he realizes his clothes are bigger and his palms are hairy. Little to his knowledge he made contact with the contaminated water, he then stares at Jenny and fears the same fate. The hair shreds up his arms and his shirt falls to the ground along with the rest of his clothes. At this point he notices the hair is covering his chest and working it's way up his neck and down his waist. He watches as his penis is engulfed by the fur/hair but is happy that his penis remains. This head starts to hurt and he feels the shape and realizes it is that of an ape, and his ears are no longer human. We watches the finalization of the transformation as his legs are covered with the hair and his feet become ape feet. Now where two kids once were are a donkey and ape, a woman walks by and tries to pick up Billy but he runs and hides in a bush.
Meanwhile while Ben is waiting for his boyscout bus to pick him up he notices a hose lying on a lawn with the water running so he fills up a couple of his bottles for the troop.
