Haley is very self-conscious about her breath. She brushes and flosses three times a day (after her meals), making sure to clean off her tongue. When she checks herself, it smells great. She's only had one cavity her entire life too. So it really surprises her that anytime she exhales deeply, anybody in her immediate vicinity fall to the floor clutching at their noses.

Can incapacitate anybody around her with a single breath.
