[BabyScooter]

are some of the fraggles related? I mean because in the first episode boober says wembly fraggle. so does that mean there related or they have different last names? just curious.

I don't think they're all related, but they do have the same last names. Or maybe they have no last names, and every fraggle is (their name) Fraggle.

...you get what I'm saying?
Because I re-read it, and got confused a little, myself, haha.
