Haha who knows. Regardless, she may be not all well, so either way, I personally don't think it's best to pay too much attention.
I just realized: can you imagine if they had a walk around ET character? I adore the character, movie, and ride, but if I was 6 and saw ET in front of me, I'd pee....I'd pee everywhere. Hahaha.
Although an ET in drag (from the movie) would be hilarious.
