Handles the graphic numbers 5C to 5F, which are the legs of the player while the player transforms. Every fourth frame a different one of these graphics is chosen at random, and the sound of a transformation is played. When the number of steps has run out the player becomes human or wulf. If the player is killed during the transformation, the death sparkles start.
