Dolan is a very disturbing creature. He is basically the Fakegee counterpart of Donald Duck. Except he's not a Fakegee. Go figure.
Dolan's hobbies range from shooting people he doesn't like, to defecating on people he doesn't like, to throwing people he doesn't like into a roasting fire. See a pattern here?
Dolan and Weegee's Rivalry
Dolan and Weegee hate each other very much. In fact, Dolan hates Weegee even more than he hates Gooby, and Dolan hates Gooby a lot. The reason for the two's hatred of each other is because Dolan is the only creature to exceed Weegee's level of mental disturbance. This makes Weegee jealous. It makes him jelly, some might say.
