Guest star from Hungary

Happened on November 15th, 2013:
I was playing with candy that looked like medications and I was watching Cartoon Network at one point. It was CN HQ. The channel was airing a promo for a Ben 10: Omniverse sweepsstakes competition (in Portuguese and English). From my bedroom's window, I could see people cosplaying as Disney princesses from a large gray ring with four strings coming from the ground. The ring wasn't good, it wasn't of the best material.
