Any idea what did this?

Some extremely small animal had left this trail on the misted up inside of the garage window this morning. There were other, smaller trails elsewhere on the window. This area is about 10x12 cm and the trails are a fraction of a mm wide.

Whatever it was, it must have been well pissed.

The one on the left was trying to draw a cock and balls but lost it's way, then casually tried to turn it into a cow, or a dog or something.
