As red Rufus, take advantage of the turmoil and enter the camp. You will find there the captain Seagull - currently a general. After talking to him, give a piggy bank to the green Rufus. Switch the control just on it and go to the pub. Reach the piglet to the bartender and with the nucleic acid to the location with sleeping children. Go to the tunnel on the right.
As blue Rufus, head towards the conveyor. Go through the pipe and go to the barred canal window. As the green Rufus, approach the window. Now the green and blue Rufus will be able to share their equipment. Switch to the red Rufus, given the green Rufus Image from Elysium, which you then pass to the blue Rufus. While controlling the latter, attach a picture to the barrel, jump into it and click Oppenbot. As the green Rufus, click on the pipe leading to the right and being at the bottom - the whirlpool.
