MacFarlane's performance as Klaus the Goldfish is probably what got him the job in the first place. Del Toro could have told him to "just use your Klaus voice," for all we know.

It's funny the entire movie I kept saying to myself jeez that almost sounds like Seth McFarlane! But there was no way it could possibly be him. Imagine my surprise when I stayed through the credits and caught his name!

Except that Seth MacFarlane _doesn't_ do the voice of Klaus.

Really? Bah! I thought he did, it just sounds like a voice MacFarlane could do. My mistake.

^To be fair, I made the same assumption. I was fairly shocked when I looked it up.
