No one seems to have mentioned that karkinos can use tools, they just need a special type of tool: doedicurus, use a karkinos to pick up a tamed armadillo and walk around to rocks and the armadillo hits the rocks and keeps them stored, argies and quetz can do it to but they can only hold one and they don't spawn on abberation, not sure but if you transfer a beaver to abberation you might be able to use it and an armadillo at the same time to gather both rock and wood
If you're carrying a tamed Doedicurus in your claw the Doedic will automatically start harvesting any stones you hover him over. Just start pumping points into your Doedic's weight because it will stop at about half of its own carry weight. I've yet to discover another tame it will work with though...
Be careful when carrying a Dino that has a tribe mate mounted on it. I was walking up a hill carrying my anky with a tribe mate on it and they went under the map and died. RIP ANKY AND SHINEHORN. Tribemate was eh anyway.
If Mr. Krabs can pick up stegos, WHY CANT THEY PICK UP TRIKES!!?!??!?!?!?!?!?!?!?!?!?!?!? Pick things up with this, and tranq them with rifle, u can do it while mounted, or, thing u want to tame in one claw, snake in the other. Boo yah! U are welcome.
An all around amazing tame with a variety of uses. Hunt trilobites for oil. Carry armadillos for farming stone and clearing paths. Delicately plucking dinos off an elevator. Exploring. Farming gems from rats. The list goes on and on, just be creative. Its almost OP but it is hard to tame. Not only do you need a catapult but you also need to score only body shots and even then pray that its strong enough to survive the hits. It's tanky, uses surprisingly very little stamina, has a good attack even without the grab, well worth the trouble.
Hands down the best water cave runner. If you can transfer a karkinos to the island they can easily run both the cavern of lost hope and lost faith without aggroing many creatures. Mosasaurs, jellyfish, and eels all ignore the karkinos making those caves a cakewalk. Even better, the tusoteuthis cant grab the karkinos either.
