Gigantopithecus are such fun creatures with the "Kraken's Better Dino" mod giving them alternative armor, and being able to use tools like the Mantis. But these Ferrox are even better! Way faster, super bunny hops, flurry attack that kills and harvests in a button press. Ferrox's look awesome as well, and it's such an interesting idea getting little creatures addicted to drugs Element, it's much more immersive than giving some other monkey like 30 berries up the butt to tame. The only problem with the Crackhead Tweakers are that taming them sucks, struggled for like 30 minutes wondering why I couldn't tame one, and once game host came over I was able to. After some experimenting turns out host needs to be in range of monkey thing, in order for me to feed it element? Anyways hope this little bit of info helps if someone googles it, since the other steam thread's or whatever those are didn't.
