I had to share this lovely picture of the scariest, angriest, don't-mess-with-me drop of water ever. Angela would like to make it clear that you really shouldn't waste water. EVER. When I asked her if that little red circle in the middle was its tongue, she looked up from her drawing to say, "No, that's a lung," and went right on coloring. Now that's passion for ecology!
