OH, ok, I misunderstood. (That's what I get for skimming. :-) The car key drawing is better than anything I'd probably be able to do right now...) I have to admit that one of the disadvantages to the fact that I had such a good art teacher is that it drives me crazy if the things I draw aren't vaguely realistic.
Although I do remember having fun with scribble drawings in one of my art classes. The teacher had one of those wooden figure models and would move it every 60 seconds or so into a new position and within those 60 seconds, we had to draw its form using nothing but scribbles - basically long, narrow ovals, if that makes any sense. Vaguely like this (http://www.artexperiences.org/circlescribbledog.htm). Natalie might have fun with those. I do remember being taught that if you're trying to do quick sketches, don't use solid lines, use quick feather-like lines. You won't get a solid edge, but it's great for trying to get a shape down quickly.
And the suggestions about looking into cartooning are good ones.
