Doozers are the small green critters that share Fraggle Rock with the Fraggles, but are only about shin-high to a Fraggle. Unlike Fraggles, Doozers are born workaholics, who labour ceaselessly to construct girder-and-panel constructions. The constructions are made of clear plastic like rods that are irresistible to Fraggles, who munch them up with gusto. Doozers don't mind because they need fresh space to build it, and if Fraggles didn't demolish old constructions, Fraggle Rock would soon be filled with Doozer constructions from top to bottom. All except for "Plumb Bob" Doozer ... the world's only lazy Doozer.
