Akiki

Akiki is a tomboyish Ukiki who is the mayor of Jungle Town in Party World. During the events of Mario Party Advance, Akiki, believing her uncle, Ukiki, to have been kidnapped, asks for help from the player and Shroomlock in finding him. If the player does succeed in finding Ukiki, he will return to his house and reveal to the player, Shroomlock and Akiki that he had simply faked his kidnapping, wanting to play a joke on Akiki. The message Ukiki had left Akiki read, "bIg teAM cAT THElf bLAKE." - the capital letters spell "I am at the lake".

Interestingly, Akiki's name first appeared in the scorechart for Mario Golf: Toadstool Tour, which was released many years before Mario Part Advance. However, while it is possible that they decided to turn the name on the scorechart into an actual Ukiki character later on, this is most likely a coincidence.
