In Mario Party Advance[]
When the player's character visits Boo Cemetery, they are greeted by four Boos, and their associated quest is True-Blue Boo.
During the True-Blue Boo quest, the Boos are about to tell the player's character about a crime that had occurred recently. Shroomlock arrives to try and help solve the crime, and the Boos mention that the Golden Boo Statue, a symbol of their friendship, is lost. When Shroomlock suspects it was stolen, the Boos become worried and ask the player's character to help find it. At this time, the Boos realize that there are four of them in their group rather than the usual three. Shroomlock tells the Boos that one of them stole the Golden Boo Statue and is an imposter among them. Shroomlock then asks the players' character to select the Boo with a slightly different moveset and rhythm, and selecting the correct impostor reveals Boo to be Koopa Kid, who flees but leaves behind the Golden Boo Statue. The Boos reward the player with the Predictotron Gaddget for their help.
In the epilogue, it is stated that the Boos now regularly haunt Horror Condo.
