Colony Square’s official events page lists Scare on the Square: Little Monsters Bash for Tuesday October 27, 4 to 6 p.m. in the Plaza. Admission is complimentary. The activities include candy, face painting, spooky arts and crafts, music and a bounce house.
The timing is deliberately after school and the venue is in Midtown, making it a convenient family outing without an all-day commitment. It is not a substitute for Saturday neighborhood trick-or-treating; it is a short event with a specific two-hour window.
What to do: put Tuesday 4–6 p.m. on the family calendar if the boys are interested, and check the venue page before departure for any weather-related adjustments.
