When trying to tame them be careful that they don't grab you off your tame because they cause stamina drain. Also on Xbox they glitch out and when they have you in there mouth they will 'runaway' but you will stay where you are but keep taking damage until you die. So you have to chase them down and kill it.
Try not to let it get close because it can jump quickly and far. Try to run uphill so that when they leap they won’t travel very far. Also their bite drains your stamina so try to avoid them at all costs.
This guy is my favourite so far, right from when I first meet him, I was a noob and wandered close to a swamp well he came flying at me missed and disappeared behind me, I'm like what the neck was that, climbed a big arse rock asap and looked around, bugger came bounding back towards me and leapt straight up that rock like it was a mole hill.
Tamed the bugger and took him hunting, came across my first raptor and shat myself thinking oh rap I am screwed, nope Kappa flys over my head, collects the raptor and pile drives it into the ground several meters away, hilarious. Always fun times with Kappa around.
