Outtakes: Two different sets
I find it odd that neither the IMDb Trivia, nor Wikipedia, mention that two different sets of outtakes were made. My Blu-Ray only has the first batch. Fortunately, some nice YouTube user put 'em both together...

When I was going to show this film to a friend, he wanted to stop the movie as soon as the credits started rolling, but I told him we needed to wait for the bloopers.
He just looked at me incredulously: "How can you have bloopers in an animated movie?"
Well, needless to say, we were both soon laughing so hard we just about horked up bits of lung!
See, that's the beauty of it: You would never expect to see things like a boom mic or a clapper in an animated project, simply by virtue of the fact that they're made in an entirely different manner than a live-action one!
