Aim the C-3PO at the TNT. It’s a straight shot that is fairly simple to make.
Power Activation Point
The power activation of the C-3PO is very tricky. You want to activate it before you bump into the TNT. Your goal is to have a piece of the robot break into the pieces so that it knocks the tower to the right, which can have a chance of setting of the second TNT bomb.
