Super Star

The Starman can be in the container items or just pop up out of nowhere.
 * Originally from the Super Mario Bros. series.
 * When someone touches it, they are granted invincibilty for 10 seconds.
 * While impervious to all damage, knockback, and grabs, is still possible to self-destruct if the character passes the blast line, either by falling, walking, or jumping past it.
