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.
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...
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.
