Karkinos dodgeball. 6 crabs, 3 per team. 10-15 aggressive ravagers from a 3rd tribe in the middle. The goal is to throw ravagers at the enemy crabs to kill them. You lose when all your crabs die. No smashing, shooting, jumping or tomfoolery. Just throwing ravagers.
My sis and I tamed our first one and it was the best decision ever. Charlotte (the Crab) has been a huge help with taming other dinos, she holds them while me and my sis pelt darts into them. Its been super fun!
When ever one of these picks you up and makes you into a pancake think about all the times you have poked a crab with a stick or accidently stepped on one. Because this is there revenge , so the next time you see a crab be nice to it or else you'll find your aberation base being ransacked by a bunch of karkinoses , it won't be pretty! They will use your tames to play tennis and use you to fish for ravagers. Possibly there friends the spines will be there too!
