Party Details

A full 90 minutes is spent on the gym floor in an action-packed event with no down time, and you have our entire facility all to yourselves! Kids learn about 6 or 7 different ninja warrior obstacles, and then put it all together and run the entire obstacle course, complete with sound effects, lights, and the thrill of hitting the buzzer at the top of the Warped Wall! Supervised open training takes place while other kids run their courses. Brooklyn Ninja Academy parties are unique in that we waste no time with pizza and cake, parties are highly organized and instructed, safe activities for maximum fun!
