As a Finn I can understand Sweden pretty well so that's why I was able to understand most of this comic.
After all I went throw some old comments to be sure to have correct translations and made summary about what they are saying.

First screen:
Sweden: I've been wondering, why do you have a fish on your head?
Norway: So that my hands are free.
Sweden: That's stupid.

Second screen:
Sweden: To have a fish on the head makes as much sense as to have a boat on the head.
Norway: A boat? Why would you have a boat on your head?

Third screen:
Denmark: Hi guys! Can I join you?
Sweden: Why do you have a city on your head? It has nothing to do with a sea.
Denmark: Yes it does! It's a sunken city!

Fourth screen:
Finland: Are you trying to mock my hat?
Sweden: No Finland. You always think that everybody is making fun of you.
Norway: What?
Denmark: What did he say?

Fifth screen:
Iceland: I also like clothes! See! Demon mittens!
Norway: They're beautiful!
Sweden: Stop! Now it's getting too stupid!
Denmark: They're scary...
Finland: Are you trying to mock me?

Sixth screen:
America: What the hell is going on!?!!?
China: I don’t know!
America: Shut up!!!

@AsFinnAsCanBe thank you my hero

@Mericagirl You're welcome.

@AsFinnAsCanBe thanks bro! You're a lifesaver)

As a self-aware American who realizes the rest of the world accommodates us to no end, I appreciate and am grateful that your comic is in English. Thank you.

@TossingTurnips Me too

@TossingTurnips
Here also. Having it in English means I've been able to enjoy, understand, and learn from this comic, and I've done all three. ^_^

@TossingTurnips yes, thank you

... Dammit, I don't speak Google Translate...

@Varkrow fuck, you made me spit on my screen X'DDD

Finland... is talking o.o

@Kyasarin we need an exercist

...And we of the native English speaking crowd, APPRECIATE your practical choice to share all your stories with us, in a format we are capable of appreciating! ^_^

I’m half Chinese, so what China is saying is “I DON’T KNOW!”

Sweden: Why do you have a fish on your head?
Norway: In this way It makes my hand free!
Sweden: Having a fish on your head is as makes sense as having a boat on your head.
Norway: A boat? Why I need to have a boat on my head?
Denmark: Hey boys! Can I join in?
Sweden: Why do you have a city on your head? It doesn’t make sense with the ocean.
Denmark: Yes,it is. It’s a sunken city!
Finland:... You can mock my hat.
Sweden: No Finland.You always think everyone is making fun of it.
Norway: Lift?
Denmark: What did he say?
Iceland: I also have funny clothes too!See! Demon Gloves!
Norway: They're beautiful.
Sweden: Stop! Now it's too stupid!
Denmark: They are creepy.........
Finland: You can mock me......
America: What the hell is going on!?!!?
China: I can't understand!
America: Shut up!!!

@OppositeAmerica
Pretty sure Norway's saying "what?" instead of "lift?".

@TheyCallMeMo China is saying " I DON"T KNOW!"

@Queen_Marie_ONE Thanks

@TheyCallMeMo What Sweden answers Finland would actually translate to:
No Finland. You always think that everyone is making fun of you.

@ryttyr thanks for the correction!

@TheyCallMeMo you welcome.
