Boober Fraggle is one of the five main Fraggles in Fraggle Rock. He has green skin and fur, red hair, and no visible eyes. He usually wears a brown cap and scarf.

Unlike other Fraggles, Boober does not like fun and games and spends most of his time worrying about doom and disease. When he's not worrying about himself, he's busy warning others. He is easily frightened and sufferes from a variety of phobias. Because of his fears, he is very knowledgeable about health and superstition. Aside from his friends, there are only two things in life that Boober is very fond of: laundry and cooking.

Boober lives on his own in a hole. He often hangs out with Wembley Fraggle and is easily annoyed by Red Fraggle's endless enthusiasm.

He is allergic to dogs.

Inside his dreams, Boober has a fun alter ego named Sidebottom (also performed by Dave Goelz).

Boober was named after an angry cow encountered by one of Jim Henson's daughters in Devon. In the language of the ancient Fraggles, "Boober" means "Tie 'em to a rock!"
