Making tracks

The Green Tree Frogs were everywhere and anywhere last couple weeks, perhaps the height of the season for them.  Windows, doors, plants, and everything else were full. 
When the weather starts to turn we get a fog on the windows.  The frogs continue to do their thing, but the temperature change gives us a a little treat in the morning.  We get to see the tracks of a frog chasing a bug, making it's way to better hiding place for the day, who knows?  The tracks are there.
I want a rubber stamp that looks just like these tracks.
Here are shots of  frog tracks on my kitchen door on a recent morning.  Aren't they fun?
