Since I'm from Brazil, I guess it's natural that I've watched FHFIF in brazilian portuguese a couple of times.
I've also watched the english version, which in my opinion is way better than the brazilian portuguese dubbed version. I mean, Bloo is really loud in the portuguese version and Cheese doesn't sound right (I'm used to watching the original version, so I've grown used to Cheese's original, creepy and incredibly funny voice).
Sorry for my bad english. XD
Here is the short called Pen Pal in brazilian portuguese:

Note: I'm not sure I should be posting this, since there haven't been many new posts in this thread lately, and this is my first post here.
