When it comes to describing a group of people who gather closely together, there are numerous synonyms that can effectively replace the word "huddlers". These alternatives include "clustering", which denotes a close formation or bunching up of individuals. Another option is "crowding", which highlights a group's tendency to come together in a tight and confined manner. Additionally, "congregation" signifies a gathering of people, while "throng" emphasizes a large and dense assembly. One can also use "mass" to represent a closely packed group. Whichever synonym is chosen, each effectively conveys the idea of people gathering closely, forming a united and cohesive group, just like a huddle.
