that bit wasn't included in the episode rip I downloaded.

Huh -- it should be, because it's in the background of some dialog. I think it's when they drag Vala away from the balcony where she's ogling Atlantis, then inside, as Daniel and Elizabeth are chatting while they walk, it's behind them. Totally woulda missed it myself, except my brain went "Hey, there's Zippy! Where'd he come from?" and I had to rewind. Take another peek? It's super cute.
