Prussia smirked as he raised the red balloon filled with helium up to his lips. France and Spain were facing him in their seats, forming a sloppy triangle. Each of them had a helium-filled balloon in their hands. Prussia put his mouth on the opening of the balloon and inhaled some of the gas. "Kesesese! How do I sound? Awesome as usual!?" Prussia asked as soon as he closed the balloon again. His voice sounded 5x squeakier and seemed to jump an octave or two. If you would hear it, it sounded so ridiculous, you'd bust out laughing. Which is just what Spain and France did.

"Fusosososo, sí, mi amigo!" Spain said after he caught his breath. He used his own green balloon, taking in some of this helium. He cleared his throat and spoke. "Olé~" He purred in his newfound high-pitched voice, wiggling his eyebrows and causing a chorus of laughter.

"Come on France, join us in the squeaky squad!" Prussia urged, grinning and nudging his friend. France tilted his mouth upwards in a hesitant smile.

"Sí, join us! One of us, one of us, one of us." Spain said, with Prussia joining in the chanting after a few seconds and sounding even funnier on the helium. France chuckled.

"Ja, we need your ohonhonhon!" Prussia laughed loudly.

"Alright, alright." France stuck his tongue out, and inhaled some helium from his blue balloon. "Oui, Mon Ami." France tested, ending up laughing at the way he sounded.

Germany and Austria accompanied by Italy walked past the room the trio was in. Germany paused at the sound of their squeaky laughter.

"I'll just... Come back later..."
