This trick will allow you to trap enemies like the Beetleworks (the bird things n the ones who throw paint and thinner at you) and the Robot Pirates. In order for it to work, you have to lure the enemy to a spot where you can thin things out, thin it out, then quick re-paint it. If you did it right, the annoying enemy will be trapped, and won't be able to move or attack. Unfortunately, if you should die for some reason, they'll be free again.
