WEST FORSYTH — One Sawnee Elementary School second-grader is getting her Halloween creep on Thursday when she will appear in a hit TV show on the Fox network. Brooklyn Garmon, 7, is set to be the focus of one episode of “Sleepy Hollow,” which airs at 9 p.m. Her character, Tessa, is the younger of two sisters who get a surprise visitor after their father puts them to bed one night. A hissing, drooling, growling monster that Garmon’s grandmother, Teresa Garmon, described as an evil tooth fairy that sucks the life out of children, puts the young girl in a coma.
