Here is a drawing of Brenda Kahn, the model for Puffy Prawn. As may be apparent from the sketch, she was a diminutive person. Along with Cindy Lee Berryhill, Brenda was on the few singers in the Antifolk scene to score an actual record contract (I guess she had more luck with the A&R man than Sarah Hauser), in her case with Columbia. She has continued to perform and record since.
Here is a video of Brenda performing her biggest hit, l Don't Sleep, I Drink Coffee Instead: https://www.youtube.com/watch?v=goTz9fLCB7A
