Boober Fraggle – is by far the Rock's most intelligent Fraggle, as well the smallest and youngest of the five, but often too smart for his own good. His cardinal traits include depression and worry, and as the Fraggle who does everyone's laundry, he most enjoys washing socks even though Fraggles do not seem to use footwear most of the time (possibly he collects them). Boober almost always expresses a nervous, cautious attitude, and displays hypochondriac tendencies (he is apparently allergic to dogs) and he expresses deeply ingrained superstitions. He has so much knowledge that he is actually a capable medic to the other Fraggles, as evidenced in the later seasons. When not doing the laundry, Boober is an avid reader, likes to share his talent as a chef, and with his knack for harmonica, has a penchant for singing and playing the blues. Boober is greenish-blue (befitting his personality) with reddish-orange hair, and always wears a red hat and brown scarf. He is the only primary Fraggle whose eyes remain invisible, and he prefers to live on his own, although he is close friends with Red and Wembley.
