Hello! There is a wiki page for More Creeps underway.

It's currently a stub as is and missing documentation for most creatures, but if you feel like contributing by creating pages then go ahead! Just remember to follow the standard wiki guidelines.

If you need any help contributing, please consult the noita-wiki channel in the discord, I may be experienced in modding but, they're far more experienced in wiki creation than I am.
That said, best of luck wiking!
