"READY!" commanded Nora. Her grin was 1 part happy, 2 parts excited, 1 part ready for action, and 100% adorable.

Ren responded to her command by hoisting their improvised potato cannon over his shoulder. It was an unholy abomination of PVC pipe, values, hairspray, and a potato. Ren pressed a switch and the pilot-light sprung to life.

"AIM!" Nora commanded, thrusting a finger at the melee taking place in front of Ren and herself. Pyrrha and Jaune were holding the line with whatever food items they could get their hands on. Pyrrha wielded a massive a 26 inch summer sausage as her weapon. Jaune was making do with a serving-platter turned shield and an oversized asparagus. Ren centered the canon's crude aiming apparatus on Team RWBYs formation, and muzzle-loaded a potato into the barrel.

"FIREEEEEE!" shrieked Nora.

Ren squeezed the trigger, the pilot light came into contact with the firing port, and all hell broke lose. There was a cacophonous explosion of flame, followed by a bright flash of purple light as Ren charged the cannon and it's projectile with his own aura. The potato departed the cannon at incredible speed, causing multiple shock waves as it smashed through the sound barrier. Nearby tables and chairs were flung from ground zero and smashed against walls.

The supersonic potato's slipstream gathered up fire and smoke as the tuberous projectile closed the gap to Team RWBY. Jaune and Pyrrha had known what was happening and dove for cover behind overturned tables. Team RWBY was not so prepared. The unholy missile roared past them at uncanny speeds, trailing smoke and fire as it went. The shockwave of it's passing was enough to lift them off their feet, and they were engulfed in the trailing vortex of flame and horror.

The potato smashed through the cafeteria's back wall with extreme force. The wall didn't stand a chance, and a rough-hewn 20 foot hole was blasted clean through, sending shrapnel far and wide. The potato did not fare any better and was smashed into mash. The whirlpool of flame and smoke followed soon after, carrying the soundly defeated Team RWBY through the breach.

Once outside, the vortex dissipated quickly and deposited the team on the singed courtyard lawn. Team RWBY laid defeated, blackened, embarrassed, and more than a little confused. Ruby was the first to try and sit up, followed by Yang, but both of them failed and fell back to the ground. The other two team members simply stayed down.

Team JNPR surveyed the carnage. "Oh..." said Nora, concerned, "Do you think we used too much?"

Jaune and Pyrrha peaked over their bunkers and simply stared at the aftermath wide-eyed.

Ren calmly placed the spent cannon on the floor of the cafeteria and replied, "No. I think it was the right amount."

Pyrrha turned to Ren and started at him with wide-eyed shock. The corners of her mouth started to tremble. She snorted once, twice, giggled softly, then broke into full-blown laughter. The rest of Team JNPR joined in her mirth.

The victorious team picked their way through the rubble, across the breach, and over to the still-prone team RWBY, laughing the whole way. One by one they helped up their fallen friends and dusted them off were appropriate. Both teams shared a good laugh.

That's when Professor Glynda Goodwitch arrived on the scene. She was not happy.
