Children throughout New England are invited to trick-or-treat among the animals. Thrills, chills and animals lurk around every corner on the Trick-or-Treat Trail. Throughout the day, guests will learn about the importance of enrichment, as they watch as many of the animals receive pumpkins, generously donated by Whole Foods Market Jamaica Plain, as enrichment items. Haunted happenings include:

Creepy crafts
Ghoulish games

Haunted maze
Face painting provided by MetroPCS (Saturday only)
Fun activities and photo opportunities provided by Fidelity Investments U.Fund Dreams Tour (Sunday only)
