In a game about collecting little critters through dance battle prowess and agriculture, you find yourself overrun with Ooblets awfully quick. Not a problem! They're adorable and only a monster wouldn't want an endless flock of these little followbabies.
Actually, it is a problem. Ooblets has a cap on the number of creatures you can tend to at once. In the early game, it never comes up. You just keep harvesting new Ooblets because you figure more is better. Some can stay home and tend to the crops, others will defend your honor through dance.
Later, once you have access to new Ooblets that you want to try out (and scan for the databasing sidequest), you'll inevitably be hit with a message telling you that you've hit your limit. The only way to add more Ooblets is to spring for more coops. That's probably not where you want to invest your resources at the moment because coops are prohibitively expensive in the context of Ooblets. They require clothlets and oobsidian, both or which are needed for several of the quests you're likely chipping away at.
The balancing of it all is just kinda off, and that's the point of launching in early access. The solution is to jettison some of those Ooblets far away so that they aren't your problem anymore. Don't worry -- they're going to a loving home where they can run around and dance to their hearts' content.
Ooblets update v0.3.60 will let you send Ooblets to the Wildlands for re-homing with Outgrid. This isn't a new playable area -- those are still in progress -- and there's no way to retrieve Ooblets that you've sent away. It's just a quick and effective method of hatching those new Ooblets without needing to grind for more coops.
This update is live on PC and moving through certification on Xbox. Here are the full patch notes for Ooblets update v0.3.60:
