On this week's Music Core, the cutesy journey of IU continued as she performed Marshmallow. She had a great performance once again but unfortunately the marshmallow mascot wasn't there. He was being roasted at a campfire. Although in my honest opinion IU is more suited to ballads... her cute dancing and singing are always enjoyable but I'm still sad over the non-appearance of the marshmallow mascot. :( Check out the performance below: cr: xumjluv78
