Smorgs are small, black cloud-like enemies with yellow eyes. They appear in the sixth chapter of Paper Mario: The Thousand-Year Door. Their name may come from the word "smog", based on their dark, cloudy appearance. It may also be a pun on the word "smorgasbord", with their role in the chapter being summarized as "Smorgs aboard" (the Excess Express). Their vocabulary consists only of the word, "Smorg". Later, they collectively form a large entity of the same name, who serves as the chapter boss.
