The only consistent things about the fellow before you is the pitch black rat that is perched on his shoulder and the fact that the figure is always wearing some sort of hat. The figure at first appears to be a dwarf with a braided beard, then a short human (or perhaps a tall Halfling?), then an extremely portly goblin. His clothing flashes from rainbow, to solid gold, to a loin cloth. The rat placidly sits on the creatures shoulder as that shoulder rises and falls as the figure grows and shrinks.
