Akiki is a character that appears in Mario Party Advance.
In the game, she has come under the belief that her uncle was kidnapped and requested that the player and Shroomlock go search for him. She left a secret message reading "bIg teAM cAT THElf bLAKE." When looking only at the capital letters, it spells "I am at the lake", referring to Loch Dorrie. Once the player has found Ukiki, he revealed that he faked his kidnapping to play a joke on Akiki.
