When Yaya's back is turned

(NOTE: In case mobile audio fails, use laptop/headphones) With Yaya as class prefect, she can choose to punish unruly classmates. When BoBoiBoy and Fang continue to quarrel despite her efforts to stop them, she makes them stand on the tables while holding weighted chairs. They still kick at each other when Yaya's back is turned, though.
