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