Ep. 12: Mayor hosts tournament for riverbank strength with wish prize
Aired on December 20, 2010
The Mayor organizes a competition to determine the strongest individual on the riverbank, promising the winner a single wish that others must fulfill. The initial stage features a battle royale among weaker candidates, which P-ko successfully wins. She subsequently competes against stronger opponents in a balloon popping contest. During this match, P-ko and the Mayor simultaneously pop each other's balloons, resulting in a double loss. Consequently, only two candidates remain in contention for the King title: Maria and Sister.
