I just noticed this last night in the forth eps. opening sequence. Right after the Man witht he hook passes in the tube you see Amy followed by that other guy with the bad haircut (Whose name I can never recall, and yes I know they all have bad haircuts) followed by Kif. I didn't notice this in previous eps. so I don't know if it is the same for the first three or not.
