 Any help?
I'm still trying to get a better shot of this, its the wierd translucent white thing between these two feather dusters. It's actually very small, probably only 1/2 inch in diameter (the whole white substance).
The tube looking things are usually open, but they do seem to sort of close and collapse sometimes, although it doesnt seem to correspond to the light, feeding times, etc.
