The event will be held at the library's Whippoorwill Hall from 11 to 11:30 a.m.
There will be a superhero obstacle course, and attendees are asked to come dressed as their favorite hero. At the end of the course, snacks will be available and you can have your picture taken as a flying hero.
The library asks attendees to bring an old blanket or dog and cat food. Plans are to donate to a local animal shelter.
The library is at 19 Whippoorwill Road East in Armonk.
