I get several fuling attacking me pretty much any night I'm in black forest, so I like to do that sometimes to watch the carnage. Best case is if I catch a troll in the process.

One time I had two spawners close together, ran between them for a while and had quite a horde before the fuling spawned! Then just stand back and watch!

You can do something similar of you find a spawner close to a fuling vilage. Running a horde of blackdwarfs through the middle of a fulling village is quite fun.
