In this event match, the objective is to KO the two Nanas on either side of the stage in less than a minute. Nana is the Ice Climber wearing pink. The Ice Climbers are located on the floating platforms on both sides of the stage. The only action the Ice Climbers do is jump. Killing either one of the Popos in this event will result in a failure.
There is a slight delay between the time that the player kills Nana and when the game recognizes their success. This is intentional, as it prevents the player from simply killing both Ice Climbers. If they were allowed to do so, the Event Match would be much easier, as they could simply hit both off the edge and have Nana die first.
