How do you trigger the event for the cloud fall after unlocking the mossy forest ?

[universeofnya]

I almost have every creature available that you can find before the final cloud fall but I can't seem to find or trigger the event that allows me to make the cloud fall again ? Also I can't seem to get the emerald burbot to spawn. I've been flying around mossy pools for hours and nothing has shown up.
Also I see people talking about feeders and I don't have that unlocked, how do I get those ?

Have you caught a crystal sprug yet, and is it flying with you? Visit the Skyfish Caverns and locate where the snoring is coming from. That should trigger things.

Access to feeders will only occur near the end of the game. They will help you catch any hard-to-find creatures.

I've retrieved the feed bag and for the life of me I STILL can't get Emerald Burbots to spawn. I'm also still having trouble with the last drupe that only spawns as like one larger and one smaller in the swamp area too, but I haven't been trying too hard to hunt for that one -- it's the Emerald Burbot that is SUPPOSED to be easy to find that seems to absolutely not spawn AT ALL for me. I fly around every mossy pond I find and zoom into it AND listen for sounds and there is never a thing and I do this for HOURS during daytime AND night time AND evening AND morning. I've even restarted the game multiple times with a full shutdown... I literally cannot get this guy to spawn for some reason. And when I put food in feeders in the mushroom forest, 99% of the time it does attract "rarer" creatures, but a lot of time it's also attracting the Rosy Trip or Common Thrip which is just a giant pain.

There HAS to be a better way for this, why in the world does this creature not want to spawn for me? Not to mention, I HAD the stupid Forest Gleeb, ran into it and went to tame it, but even when I hit the call button right at the perfect time, it decided it wasn't perfect and spooked the damn thing, so now I'm wandering around the Mushroom Forest waiting for THAT sucker to spawn again for another tame chance too, which is also a giant pain.
(But at least the game tells me where I ran into him, so I can just camp that area - that's how I found both the Dusty Burbot and the Painted Skyfish (M) both a second time because I didn't have their whistles when I first found them.)

I'm also totally stuck on the Emerald Burbots! I caught the Forest Gleeb after my second try, but I am definitely getting sick of looking in puddles for these fish >.<

I know with some of the Winnows if you have them in your flock they'll point out other hidden winnows, is there some similar trick for these Burbots?
