Karissa Mitchell knows what it's like to stand out in a crowd, which is why she identifies with Elsa, the main character of Disney's animated film "Frozen," so well. Like Elsa, who faces criticism for having trouble controlling her unique powers, 9-year-old Karissa, of Stillwater, New York, was born missing her right hand and most of her wrist. But thanks to a group of Siena College students who 3-D printed a "Frozen"-themed prosthetic arm for Karissa, the little girl is feeling more confident in her skin. "Karissa really identifies with Elsa because she knows what it's like to be different from everyone else," Maria Mitchell, Karissa's mother, said in a Siena College news release. "She doesn't want to be seen as different, which has made her extremely determined to do things as well, if not better, than others."
