You can configure so much here!
Mo-Items!
As critters are ambient, there will be very few, if any, custom items from this pack.
Integrations:
Mo-Critters contains several integrations with other packs. Please bear in mind sometimes this list may be a little behind.
All integrations are always optional, and only exist to make your personal experience better.
- Horde Nights Integration for 1.20+
- This integration blocks the spawning of critters during active negative lunar events, keeping the ominous ambiance.
There may be more, however these are the only tested integrations. If you would like a proper integration with another pack, please reach out!
