>> so why do you think people think it's so dangerous? >> there's a cage. >> despite the differences between youth mma and the ufc, both put on quite a show. with theatrical announcers, weigh-ins and even face-offs. andrea's opponent is 13-year-old unity. she's been practicing mma since she was 9 and competing since the age of 11. so you're fighting andrea today. how do you feel about it? >> i feel excited. i'm ready to go in the cage and just fight her. >> how many fights have you had? >> i've had like four or five. >> and have you been pretty successful? >> yes. >> who got you into this? >> my dad. >> are you a big fan of mma? >> yes. we started watching it and she said she wanted to get into it. when rhonda made it to the ufc, she cried.
