Profiles

 * Dr. Mario World Twitter:
 * On Sept. 22, we showed the stages of next month. THESE are the correct ones added today. Thank you for your understanding.
 * Yellow: "The second half of the Halloween World has been added! And the special stage reward is King Boo (we secretly told you about that already). I wonder if Jack-o'-Lanterns taste good? Hmm..."
