To qualify for the U4 Fes., participating units must successfully navigate a preliminary test inside a mountain cave. The process is dangerous, as evidenced when one unit is eliminated after being trapped in a cage. Happy Around! subsequently faces their own severe challenges, including a rolling boulder, a barrage of arrows, and being launched from the mountain to parachute safely. Meanwhile, Peaky P-key clarifies that these traps are designed to evaluate the DJing skills of the units. This explanation helps Rinku understand the purpose of the trials, while Muni remains bewildered by the situation.
