Flange Doozer is a moustachioed Doozer from Fraggle Rock. Flange is the husband of Wingnut Doozer and father of Cotterpin Doozer. Initially employed at the radish refining plant, Flange later becomes a Bulldoozer, in charge of his own building team.
Flange debuted in the first season episode "The Great Radish Famine," where he joined Mokey Fraggle and Junior Gorg in the The Gorgs' Garden, as per the Trash Heap's instructions. Flange thus has the distinction of being the first known Doozer to meet a Gorg, and participating in the series' first significant contact between Doozers and Fraggles.
The following season, Flange endured his daughter's contrariness ("All Work and All Play") and fell prey to the ancient Doozer vice, competition, in "The Doozer Contest." It is the fuming Flange who first hurls the helmet, thus issuing a challenge, at Modem Doozer.
Flange also appeared, in animated form, on the animated version of Fraggle Rock. With a different design (and credited only as "Doozer"), Flange makes a surprise appearance in the PlayStation game Muppet Race Mania.
