Throughout the single-player story mode in Super Mario Party Jamboree, you’ll come across Latiku in some of the worlds where he asks questions about the board you are currently on. He is usually hidden somewhere in each world but isn’t hard to find.
For each question you answer per world, you get one mini star. Completing every question also gets you an achievement to help you unlock new items, stages, and boards. Completing each world’s questions also gets you a neat cosmetic reward for your Party Plaza.
