I agree with Sammy...it seemed really short. The plot progressed quicker than I would have liked it. Had a few funny parts. Overall, I'd have to say it was just o.k...
Missing Identity was indeed a strange episode...I didn't think the plot was nearly as good as Plankton's Army, but it was a lot funnier. Hahaha "SpongeBoob". That had me laughing for a while...heh. I'd have to rate this one "o.k." as well.
