Location: Lower floor of castle, in the fire picture.
Description: A level with lots of lava, and little bullies that look like bombs.
Star 1: Boil The Big Bully Fly or walk over to the big bully. Knock him in to the lava by jumping on his head. Cross the falling steps to the star.
Star 2: Bully The Bullies Get to the island just past where the first star was. Knock the three bullies in to the lava, and another big bully will appear. Kill him the same way as star 1.
Star 3: 8 Coin Puzzle With 15 Pieces Get all 8 red coins. They are all on the puzzle of Bowser that is constantly shifting. If a piece shakes while you are standing on it, jump and kick so the next piece will slide under.
Star 4: Red Hot Log Rolling Straight ahead of you as you start the level, you'll see a gigantic cage. Get to the cage by riding a floating platform, and roll the log over to the star.
Star 5: Hot Foot It Into The Volcano Fly in to the volcano and make your way to the top along the wall to the star.
Star 6: Elevator Tour In The Volcano Go the opposite way in the volcano and ride the elevators up. A series of poles and floating platforms will get you the rest of the way up.
Star 7: 100 Coins Use the shell (select star 5 or 6 to make it appear), and surf the lava to find as many coins as possible. Run around the two eyeballs for blue coins. Finally, enter the volcano to finish it off
