A "bulldoozer" seen scooping a load of radish dust while Mokey looks on.
Radish dust is a finely ground powder made from ground up radishes. The Doozers use radish dust in the manufacturing of their Doozer sticks, from which Doozer towers are then constructed. The Fraggles then eat the Doozer towers freeing up space for more Doozer towers to be built.
