From the Super Mario Wiki
Akiki is a tomboyish Ukiki who is the mayor of Jungle Town in Party World. During the events of Mario Party Advance, she, believing her uncle, Ukiki, to have been kidnapped, asks for help from the player and Shroomlock in finding him. If the player succeeds in finding Ukiki, he will return to his house and reveal to the player, Shroomlock, and Akiki that he has simply faked his kidnapping, wanting to play a joke on Akiki. The message Ukiki has left Akiki read, "bIg teAM cAT THElf bLAKE." - the capital letters spell "I am at the lake".
- Akiki's name first appeared on the scorechart for Mario Golf: Toadstool Tour, which was released two years before Mario Party Advance.
