He's thinking "I want to take the first person I meet into my arms

スヌーピーは「今日会う最初の人を手にとって、

and dance merrily through the streets."

外で楽しく踊るんだ」って考えてる

Ok..

そうだな…

I want to take this second person I meet into my arms and dance merrily through the streets.

「２番目に会う人を手にとって、外で楽しく踊るんだ」

Right snoopy? --mmhmm

でしょ？スヌーピー？　--うん

I don't understand you.

あなたがわからないわ

The whole world is coming apart and you're dancing!

世界が大変な時に、あなたが踊ってるなんて！

Snoopy can't help it.

スヌーピーは我慢できないんだ

My feet love to dance.

僕の足はダンスが大好き

I have an obligation to my feet, you see?

自分の足に義務があるんだ、わかるでしょ？

You know, you are not as happy as you think you are.

思ってるより、幸せなんかじゃ無いはずよ

Nobody could be that happy!

そんなに幸せな人なんていないもの！

Perhaps she is right.

もしかしたら正しいかもしれない

On the other hand, Maybe I've set a new world record!

でも、僕は世界記録を達成したかもしれない！

Maybe you have, Snoopy!

そうだね、スヌーピー！
