Boober examines Wembley's baloobius.

The baloobius is a part of Fraggle anatomy, the proper term for the fringe on the end of a Fraggle's tail. The baloobius tends to flare out when a Fraggle is scared.

In the Fraggle Rock episode "Scared Silly," Boober decides to test the baloobius of his fellow Fraggles, primarily Wembley.


Uncle Traveling Matt's baloobius is hardly noticeable nor does it ever flare out, likely making him appear to his fellow Fraggles as one of the least scared Fraggles alive.
