Super Mario Bros. 3/Enemies

Most enemies can be killed either by stomping or by the fireball attack. While fireballs only provide 100 points, you can stomp on multiple enemies in one jump for additional points. The first enemy in a chain is worth 100 points, and the next are worth 200, 400, 800, 1000, 2000, 4000, and 8000 points respectively. Continuing the chain further will provide 1 extra life for each enemy killed.

Special enemies may provide a different amount of points.
