Since it has so many legs why not have an attack where it lifts up its leg and then stab it to the ground impaling smaller creatures and killing them instantly and on each leg you can have more than one creature on it and in its inventory there is a folder that says legs and if u go into it there will be things like dermis that say the impaled creatures name and if u hover over one u can either harvest it or take it off destroying the creature and when you have creatures on its legs it will get heavy and the dead creatures on its legs can rot giving u rotten meat and maybe u could make a special saddle giving the Karkinos smaller saddles or handles to where more people could ride on and use weapons or things like that hope u like the tlc
