im just gonna say, the parasaur is the biggest dino an argy can pick up BUT it only uses one claw to pick it up. i think the argy should be able to use 2 claws to pick up bigger creatures like a carno or trike.
I was out busy collecting berries for a trike I was taming. Successfully tamed the trike, so proud! Then I heard an eagle sound. Now me and my trike live inside this feather brains belly. Smells grim. Oh look I found my dodo!
