Performer(s) Appeared in Boober Fraggle is one of the main characters from the Jim Henson television series Fraggle Rock. His cardinal traits include depression and worry, and he most enjoys washing socks even though Fraggles do not seem to use footwear most of the time. Boober almost always expresses a nervous, cautious attitude, and displays hypochondriac tendencies (he is apparently allergic to dogs) and he expresses deeply ingrained superstition. He is Fraggle Rock's most talented cook and does everyone's laundry, and has a penchant for singing the blues.
