Hotter Than Hell: "S" letter
When you are spelling the "S" for "KISS" and must go through the flames, there is a little skate pipe on stands under it. You will see that there is a ramp in the middle. Go up the ramp, then it goes up with you. When you go down, it stays up. Skate down it into the skate pipe, then jump through the flames and get the letter.
