Child 1 goes through these phases where he draws something again and again and again. He goes through reams of paper and buckets of markers. People who work in offices with me are used to giving me all of their one-sided white paper (it HAS to be white paper) so that I can take it home for him. It is not unusual for me to find a pile of 20-30 pieces of paper in a pile on my desk, all with the same thing drawn on it, and all having been produced in about a 30 minute period.
Right now he draws BART tracks. The dudes you see above were a phase he went through a few years ago. I have no idea what they are or why they're so adorable; I haven't seen them in a long time, though. I just found this in the back of a drawer as I was doing laundry. What's funny about this is that it was drawn on the back of the "2008-2009 PTA Budget."
