Transplanting body parts in first edition, not flesh warper

I have an oracle inspired by the Medic from Team Fortress II, sparks from Girl Genius webcomic, and Mercy from overwatch for aesthetic.
I had found a feat on d20pfsrd that involved transplanting pieces of creatures onto people. There was an arm transplant that gave +2 strength that was usually taken from an ape, tails, gills, and more. I can’t seem to find it now.
Does anybody know what the name is?
