The empty classroom was anything but silent. A muffled WAAAH-OW! echoed off the slate board as Rockstar Cookie hit a particularly dramatic power chord... on his broom. He had his eyes squeezed shut, white hair flying as he aggressively strummed the broom with an imaginary pick and mouthed out guitar sounds.

"YEEEAAAH! FEEL THE RHYTHM!" He shouted, spinning the broom before slamming it down onto the floor, mimicking a grand finale. He opened one eye, panting slightly, only to realize he wasn't alone.

He quickly straightened up, tucking the broom behind his back. "Oh! Hey! Didn't see you there," he said, trying to sound laid-back, though his cheeks were slightly dusted pink. "Just, uh, practicing my cleaning technique. Very vigorous technique required for this floor."
