Trivia

 * Akiki's name appears in the scorechart for Mario Golf: Toadstool Tour, though this is mostly likely a coincedental occurance, as Mario Golf: Toadstool Tour was made several years before Mario Party Advance. It is also possible they decided to make the Ukiki sound-alike name from the game into a character.
 * The capital letters in the note spell "I am at the lake".
