Mrs. Ming Ming's First Worry

I hear that Mrs. Ming Ming in Henesys is worried about something... I ran into Mrs. Ming Ming in Henesys, who seemed overcome with worry. She told me that they were short on decorations for the village festival and asked me to get 10 Slime Bubbles and 20 Pig's Ribbons. I brought back all the stuff Mrs. Ming Ming asked me for, but I'm sure these decorations are not the only things needed for the festival...
