Getting a little worried

So, the snow is mostly gone. And the ice dragons have not come by since the day before the second moon showed up. I already... miss them, for some reason.

On a side note, I saw a small bit (just a few droplets) of some sort of dark blue liquid near my Heating+AC unit. I'm not sure what it is, but I managed to (via eyedropper) get a sample into a Ziploc.
