I call these gunks because they are taken from your own clogged energy. I then make them sentient to produce a task. Each gunk can handle one task at a time but will specialize in sending out vengeance back to the one who cursed you or sent bad energy your way. They can also create feelings of uneasiness to those you see fit, bring out fears and anxiety, causing the person over time to have emotional disturbance. Use wisely becuase if you are not in the right you will get bad karma. Gunks are made to not harm their human or anyone on their own unless you tell them.
