Goblin
The goblin knows what it is at all times. It knows this because it knows what it isn't. By subtracting what it is from what it isn't, or what it isn't from what it is (whichever is more infuriating), it obtains a difference, or annoyance. The goblin uses annoyance to generate disruptive remarks to drive the goblin from a state of less goblin to one of more goblin, and a greater goblin that it wasn't, it now is.
