Rama's current interjection of choice happens to be "Pickles." Make a mistake coloring, she says "Aww, pickles." Or, I coax her out of the tub, it's "Aww, pickles!"
I suspect it's from one of the morning cartoons. Could've been from Monster Allergy or Hickey Town Hero. (Betcha didn't know there was a hero - or town - named such!)
The first time I heard Pickles, I had to ask, "Ano 'yun?" Rama explains, "Pickles? Parang aww mehnnn..."
