Present Room

The Present Room is a special room accessible in Mario Party 4. The player can view presents gained from completing one of the six boards in the game's Story Mode. The presents would be awarded by defeating the hosts in a minigame. The Present Room consists of nine miniature rooms. Each room except the minigame room belongs to a playable character. Presents in the Minigame Room can be obtained by meeting requirements in certain minigames. The presents obtained differ by room.

The "Very Final Surprise"
When the player has prevailed in acquiring all the presents for a certain character in Mario Party 4's Story Mode, Toad appears to make an announcement toward them that there's one final surprise waiting to be revealed. However, this wasn't anything ordinary -- the revelation process required the lights to be turned out -- followed by a beam of light that just appeared from above shining between Toad and the character which the player used to complete their respective Story Mode process. That beam of light which Toad points upwards to is actually one of the Stars which the player has acquired throughout their entire process. The same star proceeds to reveal the said final surprise -- which is a constellation resembling the said character the player was using to officially complete their respective area of the Present Room.

When the player visits the Present Room itself afterwards, they can view that character's said constellation that was just revealed by tilting Up on the Nintendo Gamecube controller's Control Stick while viewing the character's completed area of the Present Room.

Trivia

 * According to the in-game description, every day in Waluigi's calendar is Sunday. This is not true as the calendar displays other days of the week as well as Sunday, very much like a normal calendar.
