Hetalia x Reader (The zoo! part 4)

"Sorry." He muttered, starting to walk. You followed him.
"Don't tell me that ruined your appetite!" You said. He smiled and laughed, "Ha! Nothing can ruin my appetite!"
You smiled too. More thunder boomed outside, causing you to squeak. Alfred started laughing.
"Sh-shut up!" You said, your face turning scarlet. He laughed even more and you started laughing too, after rolling your eyes. He kept walking and you walked after him, humming. Maybe this place wasn't that bad. This time, the wire you tripped over was a sleeping guy. You landed on the sleeping guy and yipped like a stupid dog.
"S-Sorry!" You said, blushing immensely. The man opened his dark green eyes and blinked drowsily at you, with a meow. He yawned and fell back asleep. You blinked, and poked him.  Again, he opened his eyes and looked at you. Then, in a low whisper, he said, "Is there... Something wrong?" Your face turned red and you jumped off of him. He yawned and sat up, looking around. Alfred peace-signed him and yelled, "S'up, bro!" The man yawned again, his messy dark hair falling over one of his eyes.
"Alfred… Are there any… Cuddly cats… Around here?" He asked Alfred in a whisper. How did these people all know each other?!
"Haha, no! I think the lions are dead, or something. 'Cuz they're not responding to my hero voice." Alfred said in his loud voice.
"Oh…" The perma-stoned guy said.
"Haha, dude. I forgot your name." Alfred said, smiling wide.
"It's Heracles." Heracles said, yawning.
"Are you Roman?" You asked, tilting your head to the side, slightly. Heracles' eyes widened ever so slightly and a puff of smoke came from his head.
"no… I'm Greece..." He whispered angrily.
"oh…" You said,  shrugging.  Wait… Greece?
"Do you mean Greek?" you asked. He was asleep again. Alfred laughed and said, "Lets keep going, bra!" You shrugged and followed him.
"Heracres-san." You heard Kiku say behind you. He was kneeling by the sleeping Greek guy.  Weird… Everyone knew each other.
"Haha! Romano! You look so cute when you're angry!" A spanish voice was saying.
"Damn you, Antonio!" A rougher voice replied angrily. You looked up to see Feli… Except, he had darker hair and his eyes weren't closed in that clueless, sweet expression. They were golden and angry. A taller man behind him with tan skin and friendly green eyes was poking him.
"Oh! You're Romano!" You said, pointing. The Romano one looked up at you, a glare on his face.  
"I know Feliciano.." You explained, blushing.
"That damn imbecile knowsa you?!" He cursed, closing his eyes angrily. He and his brother didn't seem to have a lot in common…  
"Hahah, Romano! You're swearing around a girl! You're sooooo bad!" Antonio said, smiling brightly. This caused you to blush even more.
"Dude, let's keep going. I'm still hungry!" Alfred said loudly.
"Bye!" Antonio called after you as you walked away.
"Bastardo.." Romano muttered to Antonio, who laughed. You were getting confused as the day went on. All these random people showing up and knowing each other. They were all so different, and from what it sounded like, from different countries. What did this all mean?
