As she was lining up for the snow pit with her mother Rachel Muir, another mother and her two daughters began to verbally abuse the young girl.

"The lady in front of us turned around to Samara and said 'I don't know why you're dressed up for because Queen Elsa isn't black'," Ms Muir told The Courier.
