Retrieve means to get. So, you can buy it off a different planet and then give it to them, or simply get it off one of your blue spice colonies (if you have one) and give it to them. You could also be a thief and steal it off another planet if you have little money. You might see small boxes on some planets, near cities. Abduct these. They have spice in them. The color of the boxes shows the spice color. All is fair in love and war, until I show up ~~FNRKK 14:49, September 1, 2009 (UTC)
