King Tut is a Koopa Troopa introduced in Mario Pinball Land. He resembles Tutankoopa from Paper Mario.
King Tut is considered to be one of the toughest bosses ever in Mario Pinball Land. He floats and throws shrinking spheres at Mario. To defeat him, Mario must be large and then hit him before the sphere gets into him. If King Tut is defeated, he leaves his key and it's brought to the statue in Bowser's Castle. He reappears in a boss fight in Bowser's Castle after Mario defeats the Pokeys.
