GHOST: Begin with a bumpy, horizontal line with squiggly lines for arms. Bring the squiggly  line for the arms into a tail, add two eyes and a mouth. Presto, a ghost!

BAT: Start by drawing two ovals for the body. Add wings and some pointed ears. Add details to the the wings and face. Add feet. Fly away bat!

WITCH: Draw an egg shape for the witch's head. Draw the outline for her hat. Add hair and a big, ugly nose. Color in her hat and face and give her a mean face. If you're using markers and the facial details are lighter than the background color,  put in the details of her face face first,  then color around them.
