The third one needs to go into a room with a bed and a storage place for kibble. Put two of them into the mutation chamber of Pawnmorpher and select blackspider as mutation goal for both. Had to kill 400 guinea pigs which killed the tps after enabling the feature. Warning: this applies to all animals on the map, and sometimes they really f* like rabbits. Enable animal reproduction in the settings of Rimjobworld.Just remove the private parts (Rimjobworld) in a hospital and keep them cool. You need a male and a female ovipositor which can be gained by operating the subjects. Wait for a black hive attack and use a suicidal colonist to tag a blackspider with a tagging gun (Pawmorpher), which saves the genetic profile.Required mods: Alpha animals (for the Blackspiders), Pawnmorpher and Rimjobworld, SRTS is a big advantage for buying additional reuqired goods. It took a while and at least 2 ingame years until I found a method.
