The name is pronounced "Boogie Boy"—the strange spelling "Booji" resulted when the band was using Letraset to produce captions for a film, and ran out of the letter "g".
Booji Boy has traits of a simian child and typically wears an orange nuclear protection suit.
He had kept a supply of Booji Boy masks for several years, but due to improper storage, many of them ended up ruined from dry rot.
He also appeared in the 1982 Neil Young film Human Highway in a very comical yet unsettling role predicting the end of the planet.
In recent years, Booji Boy's concert appearances have seen him dressed in modern "hip hop" attire (including a sideways ball cap and sporting "bling"), with Devo bass guitarist Gerald Casale introducing him as "Boogie Boyyyyyy".
His only album appearances are the song "Puppet Boy" from Shout, Devo's cover of "Bread and Butter" by The Newbeats and a re-recorded vocal track to the early demo "U Got Me Bugged", which appears on the soundtrack to Devo Presents Adventures of the Smart Patrol (performed by Pat Tierney instead of Mark Mothersbaugh).
