Children throughout New England are invited to trick-or-treat among the animals at Stone Zoo. Thrills, chills and animals lurk around every corner on the Trick-or-Treat Trail with treats provided by companies including Whole Foods Melrose, Cascadian Farms, Honest Tea, Pretzel Crisps, Bare Snacks and Plum Organics. Other haunted happenings include creepy crafts generously provided by Michaels of Stoneham, ghoulish games, costume contests and a haunted maze! Throughout the day, people can learn about the importance of enrichment as they watch as many of the animals receive pumpkins, generously donated by Whole Foods Melrose, as enrichment items.
