The thought of Vinyl walking around with a cookie jar stuck on her head amuses me...a lot...
Also, given the look on Nurse Redheart's face, I think it's safe to assume that Vinyl must be a regular.
Fun Fact: *twinkly flashback music* Back long, long ago, when I was only about four years old (If memory serves me right) I actually had an orange pot on my right leg from the knee downwards after an accident involving my older sister and a handmade oak bedside cabinet. I was the snazziest kid around with that thing! XD
