The minigame has no differences when played at night in Mario Party 6, except the streetlights are turned on to light up the area where the players compete.

A Shy Guy bursts out of the post office, which is filled to the roof with mail, as the roof bursts off the top of the structure and letters fly everywhere.
Players must earn points by picking up the scattered mail and giving it back to the Shy Guy. Players automatically grab letters and hand them to the Shy Guy on contact. Regular white letters are worth one point, while pink love letters are worth three points. Any player with the most points by the end wins.
In Mario Party 6 and Superstars, the losers line up in the center of the area, with the winner(s) standing in front of them as the camera angle switches to a frontal view. The Shy Guy then cheers from behind as the players perform their victory and losing animations. It is possible for there not to be a loser.
