While trying to stop the Equestrian Magic fused Lucky Shot’s rampage, the Turtles and Rainbooms ask Belle Harmony if there’s anything that’ll calm him down long enough for Twilight Sparkle to use the Tracker. When Belle mentions that music calms him down, The Rock N Beats grab their instruments and rock out, calming Lucky down and allowing Twilight to use the Tracker to turn him back to normal, while the judges and audience members cheer the young band on.
