Looks like Peter is the Wolf is still getting more popular! Just today I stumbled across an ongoing Spanish translation:

Looks like the translator has gotten up to chapter three so far. Haven't used Spanish since my college class in it, but according to Google translate it seems like from the comments people are liking it!
Both this and seeing PitW mentioned on a Polish MLP board was pretty neat. I wonder how much of an international audience WLP has?
