some enemies don't have sprites rn, so it's prolly that. but could you say which enemies dont have them specifically? it's not likely it's a bug about a missing sprite but just asking to be safe.
I played a long time ago and if I remember correctly, there was more "pics" or "stages" when enemies libido rises. I must say I haven't been in the wolves den nor is it an option for me at this time.
if I remember correctly the wolves have a unique thing that needs to happen before the other variant is unlocked. so like that ones actually special lol
