A year or so ago, I had that mod. I really hated, in a game like starbound, that there were premade creatures showing up alike on so many planets. My whole attraction to the game was the idea of vast diversity. So there was a mod that got rid of them... poptops and creatures like that if I recall. I've searched and searched the workshop for days, every keyword I can think of, and I'm getting no hits. I don't remember what it was called. Anyone know?
I don't know if there's still a mod for it, but you might be able to change it yourself with some somewhat simple modding. In the "Modding Guides" pinned thread there should be a guide on how to unpack the .pak file. You may be able to find something in there that changes the spawnrate of unique monsters, or changes what types spawn on which planets, and remove them from the spawn pool. Should only take you a couple of hours to learn how to do it, the video explaining the process is fairly good.
