Another "thing" (77v)

[Koen G]

I was going over the nymph objects again and I can't remember if anyone has ever found a parallel for this one:

   

It's not just the identification of the object itself which is problematic, but also the way it is held and the pose of its nymph. 

• At first sight, one would say that she is holding it in her mouth, but if the drawing's accuracy at this scale is to be trusted, this is not the case. the object appears to pass behind her face, against her cheek. 
  
• Her hair appears to have a knot in it where the object crosses it, which raises the strange possibility that it is in fact tied to her hair. Again, this is hard to tell given the size of the drawing.
  
• Her lips slightly part, as if she's blowing at the object. An important note here may be that in a first pass her face was drawn slim, but then a curved line has been added to her cheek to make it appear puffy. This lends credibility to a "blowing" interpretation. Or whistling? 
  
• Her arms are held in an unnatural, even impossible position. Challenge: find a large mirror, stand in front of it and hold your arms like this. It will only work if you're made of pudding. Their positioning is more appropriate for wings (bird's or angel's). 
  
• The base ends in a weird leg with three "toes".
  

The nymph appears to be blowing over or into the object, which has been marked with a black spot. This spot looks intentional, it is not just an overly thick line. From the object some kind of lines are connected to the water below, and blue marks have been applied to the lines, possibly also indicating water.

So... Anyone?
