There's a likelihood that Monty himself didn't do the animation for this episode.

He's not the only one after all, there's quite a few animators under his wing.

In a bit of unrelated note, Monty himself had mentioned in DeviantArt couple of years ago that he's been getting sloppy a, trading efficiency for speed.
