Robo Duck Outfit
The Robo Duck Outfit combines Robo Duck Head and Robo Duck Shirt into a complete look in 
Duck Life: Space.
Getting the outfit
Buy 
Robo Duck Head and 
Robo 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.
