Note: If you learn how to pronounce them I'm sure you'll get it right

If you want it ENGLISH here:

Hey, hey Papa!
Give me wine!
Hey, hey Mama!
Hey, hey Mama!
The bolognese that I ate before,
I cannot forget the taste!

Draw a circle, that's the Earth
Draw a circle, that's the Earth
Draw a circle, that's the Earth
I am Hetalia!

Ah, with the single swipe of a paintbrush, a wonderful world can be seen
With our boots, let's make a toast! Hetalia!
