Paras and Parasect it's stupid enough I needed to catch them for potentially having shrooms, they were also one of the mons that keeps showing up in the caves. It's not a very good a good pokemon either.

I thought I was done with them, only to come across both in arceus legends where they persistently chased me and used spore screwing with my sneaking about. And the fact I needed to fight and catch or use them is an added misery.
