The good thing about establishing local wildlife as part of the scenery is that later you can use them in increasingly significant ways. You can consider doing this if you have a plan for using seemingly innocuous animals as a threat or annoyance later. Introduce them in advance and let your players think they're harmless. Only to discover later on that they leach magical power from all their items, or they suck blood at night, or whatever. Or maybe they become useful in other ways, as an emergency food source, or a way to send a message or something.
Commentary by memnarch (who has not seen the movie)
Or we could go back to Achoo again. It's been a little while since we've seen Chewbacca, however, so that's nice. And I see the porgs have been designated the little mascots for this part of the movie, otherwise they'd probably have been left off screen. Artoo must be busy plugged into the ship or something as well, though he also doesn't need more screen time in order to be merchanisable. Porg plushies probably were pushed a bit before Baby Yoda took over. That thing was impossible to avoid, though I do know now that's not from the movies at least.
Huge progress extremely rapidly could be extremely interesting! With results such as "where's the nearest refueling station" or "where'd half the ship go"! I do wonder about the radio silence part. Chewie wouldn't need a headset on if he's just doing ship repairs or tests. Hmmm. Maybe Ben will take the advice to heart and just leave the planet! Admittedly, this would mean we're leaving Luke behind for no reason and simply snipping off the training plot thread on the movie side, but that'd be extremely amusing from the comic point of view.
GM: Time to go back to Ahch-To.
GM: Now that Chewbacca has been feeding porgs, they’ve colonised the Falcon.

Rey: I’m off learning the Force so I can kick ass, and you’re in here keeping pets.
Chewbacca: Delicious, delicious pets.
Chewbacca: Given you wanted radio silence, there’s little else I can do, bar tinkering with the ship’s systems.
Chewbacca: I am endeavouring to discern what else the Peace Moon hyperspace modulator can do.
GM: You’ve found yourself slipping into indeterminate reveries, trying small experiments only to discover hours have passed by.
Rey: Do the opposite of whatever you’re doing and you’ll make huge progress in a few moments.
Chewbacca: Oh, you think science is easy when you've stranded us here on a deserted island without coconuts?
