Enter the castle and go up the stairs all the way to the right. Enter the room and jump through the painting on the right. Go through the level collecting fifty or more coins and complete the level to get an extra life. This may be done as many times as needed as you will not lose a life if you fall off the track. Note: Hit the blue coin switch first to get fifty coins much easier.

Go into the basement after you have unlocked it. Leap into the picture of the fire with a face on it. After you have retrieved the first two stars, you will make a box appear above a platform off to your left from the beginning of the level. Open the box and you will get a turtle shell. Ride the shell around the lava to find plenty of extra life mushrooms.
