In many episodes, he is shown as being a selfish younger brother, or coming up with or being suckered into some scheme to keep out of trouble or obtain his desire of the episode. When the boys first moved in with Mr. Drummond, Willis wanted to move back to Harlem, while Arnold was satisfied with their new surroundings. Willis eventually changed his mind, and they decided to stay with "Mr. D.," as the boys initially referred to him. In another episode, Arnold has to fight a school bully named "The Gooch," so that he will not pick on him anymore. However, Mr. Drummond does not want Arnold fighting the bully, and ultimately decides that Arnold must make peace with "The Gooch."
