How To Do Dangling Animal Ears

Hi there,

I really apperciate the communities help here.

I am trying to understand how to do dangling ears like the below character. (Bunny Dude) I understand how to put "Dangle" handles down on my own design, but can't seem to figure out how the below character's dangle handle on the bottom of the ear is connected to the nose. How did it get that dotted line, how was it connected? I have some experience with the stick tool, but this looks like it is using something else?

Thanks so much!

Any tutorials on this would be helpful as well. 

Also - I tried to label the ears as arms in one of my designs to control the ears with my arms instead of the animal is that possible?

Thanks,

Diana
