"Wait, what?" Louie asked - he'd run into other Fraggles down in Fraggle Rock, last time, but those were definitely not whats - they were whos. He had slowed down already when he heard some sound coming from around the nearest turn in the tunnel, at which point he came to a complete stop.

Fortunately, this was another of "other Fraggles down there" - a group of three were chatting softly as they rounded the corner, and stopped upon spotting Louie and Gobo.

"I don't think we know this one," one of them said to his two friends, focusing on Gobo.
