Lugnut Doozer

From Muppet Wiki

Lugnut Doozer appeared in "What the Doozers Did", an episode of the animated version of Fraggle Rock. Along with Rhinestone Doozer, Lugnut objected to what he perceived as Cotterpin Doozer's failure to do as ordered, and her pre-occupation with plans for a floating Doozer construction. However, when the floodwaters came, Lugnut quickly changed his mind, recovering the plans and helping to organize construction of the floating vehicle.
