It’s not often that Little Red Riding Hood gets together with Batman and Tinkerbell. But, at the annual Character Day Parade at PS 165 in Brownsville, Brooklyn, anything can happen when students dress up as their favorite storybook characters on Halloween. “It’s a tradition,” said Chapter Leader Antonette White. Students paraded around the perimeter of the school on Oct. 31 while some 30 parents and other volunteers distributed pencils, books, stickers and note pads, in addition to lollipops and healthy treats such as raisins and granola bars. “Everyone pitches in,” White said. Veteran paraprofessional Stacy Williamson said the parade has taken place for well over 17 years. Staff members get in the swing of things, too: The principal donned a Scooby Doo costume, the parent coordinator came as a big crayon and Williamson donned a purple cap to become Sneezy, one of the seven dwarfs. Williamson came up with the idea of creating a pumpkin house in the schoolyard for the school’s 3-year-olds. “They all went home with pumpkins to decorate,” she said. Donna Session, a pre-K teacher, said the Character Day Parade was fun but purposeful, too. “It exposes children to literacy in another way,” said Session, who dressed up as Pete the Cat. “Children identify with a favorite character, and they see their teachers excited, too.” Session read to each child the story featuring the character the child chose. If a child dresses up as a character with no story readily available to read, Session improvises. “One little girl was ‘Spider Girl,’ so I read about spiders to her,” she said.
