|First Game||Paper Mario: The Thousand-Year Door|
|Appearances||Paper Mario: The Thousand-Year Door|
She refers to Mario as Cutie, Sweetie, Honey, and Sugar. Peeka also seems to be a bouncer for the Pianta Syndicate. The person who wants to enter must buy items in a specific order, and then Peeka asks questions to be sure they didn't stumble on the order by accident. After the correct answer is given, she opens the door that leads to the main building of the Syndicate. Her sister is Lahla, the Boo that works at the Pianta Parlor, next-door to Westside Goods.
