Susie Derkins's mother was seen in one strip from the waist down (looking like Calvin's mother from the waist-down). She was also referenced by Susie in another strip, and in one instance she called Calvin's Mom because Calvin dropped a snowball on her head from the top of a tree as stupendous man. She appeared when Calvin was trying to smash Susie with a giant snowball. When he is caught he quickly claims he is selling the snowballs.
