Yo yo yo, Derwap the M.I.L.L. here, rounding up the troops for transport back home. Now, you don't have to be Sherlock Holmes to see that my M.I.L.L. buddies are so geeked up to be leaving their ramshackle barracks behind that they're dancing! However it appears their excitement has them milling all over the place and they are out of formation. It's up to you to put them in order and get the party headed back to Mars.
