Ha.
This translator seems interesting. Someone tells him in an interview: So you added 'Leuk hè!' ('Isn't that fun!') in this and that chapter, and I wondered what the original sentence was -- it didn't exist!
And he answers: Yeah, Naptha is getting really agitated, and suddenly I added 'Leuk hè!' and I figured, hey, I'll leave that there.

...OOOOOOK? That seems like an interesting way of translating.
'Yeah, I was just translating, and suddenly I felt like adding 'Meow?' in the middle of the book. What, you don't agree? Sucks to be you!'

:P
