Nicest Character in Fraggle Rock?

all of them

I bet not being silly and pretending not to like something so great as silliness is a pretty silly concept for such silly Fraggles (if that makes any sense )

I would go with Wembley and Mokey Fraggle 100%.

Wembley is Gobo's best friend and roomate in their cave. Not only is he smart, he does try to help others even though he has trouble making decisions. In "A Tune for Two," he stood up for Cotterpin for wanting her to be in the Fraggle Duet-a-thon. Also, his stomach (laughs)! instead of his head tried to tell Gobo not to go to Great Rock Ridge 'cause there could be a rock dust storm. I remembered that he was allgeric to rock dust. Finally, when Junior was a size of a Fraggle, Wembley stood up for his friends that he is like a brother to them. Otherwise, Wembley is very nice to his friends. How does Wembley normally when panicked? You have to turn him upside down. (laughs)! I love you, Wembley!

Mokey by the way is my favorite Fraggle, because I write, sometimes draw for fun, and sometimes quiet. Anyone who mentioned that she baby-sits Wembley. That may have been true. Although her friend Red is tough and sometimes mean, they do at times have to learn how to get along even if it means living together in a cave. So, Mokey has made some mistakes including getting her friends into serious trouble, but she can learn from her mistakes her friends got into.
