Sidebottom is Boober Fraggle's psychological alter ego, a separate personality who lives in Boober's dreams. He is Boober's fun side that he always keeps at the bottom; hence the name Sidebottom. He loves having fun and telling jokes, and his outlandish feathered hat is in contrast to the staid, laidback Boober. Though normally kept repressed within the world of Boober's subconscious, encountering Boober and others only during dreams, sometimes he comes out to play.

Sidebottom appeared in the Fraggle Rock episodes "Boober's Dream," "Boober's Quiet Day" and "Sidebottom Blues."
