If on Genesis Unofficial and want this guy, grab a bola, some tranqs, and go to Ocean Southeast. They are everywhere here and land all the time. If starve taming, teleport to the Arctic N, kill all the Sabertooth Salmon in the frozen lake with a sickle, teleport back, and bam, you have yourself an organic polymer machine!
I didn't saw anyone saying thing but if you go near one with a boat and just stay still they actually come and land on one of the edges of the boat. After that just bola him and shoot so you can tame him safely on the boat. Bring alot of narcs because torpor does come down quite fast and it takes alot of time for him to eat.
