Star Stamp

Star Stamps are objects collected in the Story Mode of Mario Party 3. When the fake Millennium Star falls from space, Mario and his friends argue over who has the right to claim it and be named the Superstar. A Lakitu suggests that they should have a contest to settle this problem. The Millennium Star comes to life at that moment and says that whoever obtains all seven Star Stamps&mdash;each named for a different quality&mdash;can claim the Star. The characters are to compete for each Star Stamp on a Battle Royale map related to the Star Stamp's trait. If the player wins, the Millennium Star begins to award the Star Stamp but is interrupted by a character who did not compete in the Battle Royale. This character claims to be the rightful owner of the Star Stamp thanks to a greater claim to the quality it represents. This conflict is then settled by a duel between the player and said opponent on a Duel Map.

After the first five Star Stamps have been collected, this pattern is broken. Daisy enters too soon, interrupting the Millennium Star and claiming to be the rightful owner of the Beauty Star Stamp before the Battle Royale has even taken place. The Millennium Star comes close to falling for her beauty and awarding her the Star Stamp without contest, before ultimately letting the player duel her without entering a Battle Royale first.

Then, Waluigi steals the Mischief Star Stamp and challenges the player to a fight on Waluigi's Island. Since he takes part in the Battle Royale, there is no duel for this final Star Stamp.

Bowser also tries to lay claim to the Star Stamps but is completely unsuccessful, often arriving after the Star Stamp has been awarded.

The Battle Royale map used to earn a Star Stamp, the character who challenges the player over it, and the Duel map used to settle the challenge are listed in the chart below. If the player chooses a character other than Luigi, he fills that character's vacated spot, but the location of the duel remains the same. As Daisy and Waluigi cannot be chosen by the player, Luigi does not replace them.
