Catch You Letter

Catch You Letter is a 4-player mini-game in Mario Party 6. It involves catching lost mail and returning it to a Mailman Shy Guy. This minigame's name is a pun on the phrase "Catch you later!" There's also a page on Miracle Book that contains the mini-game

Gameplay
Players must run toward a letter in an envelope, automatically picking it up. The players must then catch up to Shy Guy and collide with him; the character will automatically give him the letter and the player will receive a point. Regular white letters are worth one point, while pink love letters are worth three points. Any player with the most amount of points win. There can be more than one winner in this minigame.

The mini-game has no differences when played at night, except the streetlights are turned on to light up the area where the players compete.
