Stranger things have probably happened, astronomically speaking.

When it's been long enough that he has a sense of how the moons are behaving he picks one to navigate by and a direction to navigate, and goes in a straight line in case that lets him find anything else.

After a bit he sees something in the horizon. At first the faint light looks like it could be dawn, but it eventually resolves to an enormous cloud of firefly-sized bugs, moving slowly as a swarm in the air higher than Cam is flying. From this distance, it looks almost like an aurora, the bugs too far to resolve into anything but gently swaying points of green light.

Oh, cool, he'll head that way and see what they're up to over there!

They seem to be mostly just... drifting? Migrating?

"Good evening!"

No response. Not a buzz or a change in luminosity or flight patterns.

Maybe they didn't get the newsletter or whatever, this bunch. He'll go around 'em.

There's a short rumbling from underground—

—and then a sandworm like in Dune or something the size of two schoolbuses jumps out from the sand like it's so much water with surprising speed and force, aiming for the bugs but in a trajectory that will easily intercept Cam. It has three jaws in a triangle and a scary number of teeth.

Yeep! He can fly but he's not an aerobat! He tries to get out of the way but that thing is big and there is a lot of way to get out of!

Yeah no. He manages to get out of the way enough to not be swallowed whole (which is more than can be said of seventy percent of the flying bugs trying desperately to escape), and plausibly the thing's mouth isn't actually large though to do that without difficulty, but it's not enough to avoid getting chomped.

And then gravity starts doing its job.

Cam is not, or at least not very, afraid of teeth. He's willing to grab onto teeth to try to climb out of this mouth rather than go down its throat and have a really tedious time of clawing his way through organ systems.

To the extent this thing has the ability to do so, it looks kinda confused by the fact that Cam didn't go crunch. Its jaws aren't all that mobile so the best it can do is try to open and snap them shut several times to see if that'll work. It's got sticky, slimy, corrosive saliva to help with that, though.

Sticky and slimy work on him normally! Corrosive is annoying but not going to be a big problem on the relevant scale. Kick kick grab flail!

The thing is squirming on the sand, not having dug down into it yet, and there's only so much the physics of its makeup can do when it's got no opposable thumbs nor the ability to really chew, so Cam is making progress, and will be able to escape if he keeps going and if the worm doesn't try to burrow. 

Unfortunately it seems to have realised this and is starting to try to do just that.

Fortunately (?) a second, much bigger worm, big enough that it could have swallowed Cam whole if it had been the one to attack, chooses this moment to show up from underground and bite off the middle third of the smaller worm in one go. This has the effect of making the smaller worm cease its activities altogether.

...can he scramble out of the dead maw before the new guy decides it wants dessert?

Yeah, he can. It seems entirely uninterested in the tiny morsel that is Cam when it's got a much better meal in the other worm.

Nature red in tooth and... they're worms so not claw... are his wings too gummed up to fly.

They sure are. 

Also, there's now a kid sitting atop a sand dune, appearing out of nowhere and laughing their ass off. They're a very weird kid, though, with white hair and slitted eyes and a thick, fleshy-looking scarf of sorts around their neck.

"......hello?"

"Hi!" they call back, grinning. "That was so much fun!"

"...was it." How amemable is this gunk to being groomed off his wings with some combination of his hands and sand.

Pretty amenable, it's not doing so good in the cold night.

"Yeah! We were totally right that it was a bad idea to try to eat you but it was fun to watch just how bad!"

"You coulda just asked me."

"Oh, we could've, but the us that ate you probably couldn't have, I don't think we knew how to talk. I'm actually not sure any us other than us can do it!"

They hop onto their feet, then two pairs of bug wings emerge from their back and carry them down the dune towards Cam.
