You were at Americas annual Christmas party, all the nations (maybe all) had should up. You were hanging out with the shit-Imean awesome trio much of the day.

You paused your conversation and told them your gonna go get a drink. A certain little albino man felt like tagging along. "I'll go with (y,n)!" Y'all made your way to the table that was filled up with beverages and snacks. You got a cup of (whatever beverage floats your boat). "Wait!" You turned towards the direction of the voice.
"What's up Gil?" You set your drink down on the table. "Look! Over there! Uhh....there's a baby puppykitten?"
"What?" You turned to look at the nonsense he pointed out. "Gilbert, there's no-....what did you just put in my drink?" You caught Prussia, he froze right when you caught him but managed to drop something in your drink. He came close to you and whispered in your ear. "You'll see in a minute.~"
You just blushed at the close proximity of him to you. You saw him vanish away in the crowds of many countries.
You grabbed your drink and took a look at it.
"....I...Prussia you absolute shit box I swear..." In the drink there was two little spongey looking dinosaur shapes, the other pill was dissolving currently turning into another little sponge dinosaur.

I swear Prussia your just a sinamonroll. He probably keeps like a whole bag of these pills around at parties.
