In the third part of the game Screw The Nut 3, you will continue to help the octopus with deep sea work. A certain valley will appear on the screen in front of you, which is deep under water. At a certain point, you will see the bolt installed. There will be a nut at a distance from it. You will have to examine everything carefully. You will need to move certain items while making moves. You will need to place them so that the nut rolling over them hits the bolt. Thus, you twist it and get points for this action.
