While fighting on "The Portal Stage" in a one or two player game, you can fight Smoke by doing the following. Dan Forden must appear at the bottom of the screen and yell "Toasty!". Hold DOWN + Start when you see Dan Forden. Once you meet all these requirements, you will fight Smoke at "Goro's Lair". Note: Dan Forden will only appear after an uppercut. His appearance after an uppercut is random.
