Droid Duck Outfit
The Droid Duck Outfit combines Droid Duck Head and Droid Duck Shirt into a complete look in 
Duck Life: Space.
Getting the outfit
Buy 
Droid Duck Head and 
Droid Duck Shirt at 
Moon Shop for 50 
Coins each. Equip both pieces on the same duck through duck selection.
Wearing the outfit
The hat covers the head, and the costume covers the body. Wear them together for the full outfit, or mix either piece with other clothing. Clothing does not improve racing skills.
