I’m sorry but I can’t seem to translate what the text in the image says.
Could you please tell me?

Also, why does Luxray look so sad? Did something happen to him?

OK.
I read English a little.^w^

Because someone stole his pants , and don't return it.

Ah, I get it!

I wouldn’t want anyone steeling my pants either!
Being a raccoon-dog in the U.S., I need to hide my “kintamas” because censorship is a lot stricter here than in Japan.

Oh, and the text: “Please return my pants.”
Thanks for the translation! I couldn’t figure out what that character was in the lower left corner.
I use an IME pad to write characters I don’t know the pronunciation of, but the IME kept suggesting characters that didn’t look anything like what I was trying to draw.
Because of this, I couldn’t enter the text into the translator, I use Babel Fish.

He says
"ねぇ・・・　スパッツ返してよ～"

Ah, now I get it! Thanks! ^-^

You're welcome,^w^

I think what he's trying to say is that someone took his leggings. And I believe that leggings=pants (of sorts) in this situation...

Thanks ^w^
I will take care of words.^w^
He says "Please return my pants".
