I'm trying for a galarian mr. mime egg for my egg dex, I just wanted to make sure I'm not getting a bunch of the wrong egg by mistake. do I still need the incense?

nope. incense is for jr.

I uave two Baflammet at 99% breeding chances/ inseperable and have been clicking for a while. But they are not producing eggs still. Do they need to be holding something?

You actually want https://pokefarm.com/forum/thread/230017/Exclusive-Hunting-for-Dummies as Baflammet is an Exclusive and not a Variant. The answer is though, Exclusives are hardered for the most part to produce eggs as they have a much lower chance to produce at all.

Is breeding gender specific to get Snichu?

You can only breed Snichu by having Pokemon of the Snichu line. https://pokefarm.wiki/Snichu_Line

okay! I've gotten off my lazy butt and have done a big ol update to the variant list. I now have all the recently-added variants, and have also added some much-needed hideboxes so the post isn't 10,000 miles long like before. Unfortunately, as far as I'm aware, no new breeding methods have been implemented/discovered since the last time I had updated the guide. Please keep me posted if a new breeding method is discovered!

I've noticed some people seem to have guild Wigglytuffs that were bred from another guild Wiggly and a regular Wiggly without the 5 ivs. Does anyone have any idea what the chances might be of getting a guild Igglybuff from that sort of pairing?

i might be silly but i put a plusle and minun in the daycare and its giving the unexpected message? is it not a varient :0

It is not a variant but you'll get Minun eggs from them instead of Plusle eggs. Where as if you breed two Minun or two Plusle you would get only Plusle eggs.
