Playing as Luigi, the player faces Bowser while teamed up with Peach on Bowser's Castle with a time limit of 2:00. Bowser tries to attack the player and Peach, and Peach walks back and forth across the stage instead of attacking. To complete the event, the player must prevent Peach from being defeated until the time runs out; if Peach is defeated, the player will fail the event. Both the player and Bowser have unlimited stocks. Also, the Thwomp hazards have been removed, so they will not damage Peach.
The ranking the player gets is based on how many times the player KOs Bowser before the event ends. The specific conditions for this are listed below.
