As a mobile player I feel the pain of never being able to tame this do to it needing griffin kibble we the ARK mobile players DEMAND a change we want to tame them with carrots like play station players can arrow if you support
If it won’t allow you to feed it, knock it out and let it wake up then try again. Most likely due to the fact someone else tried to tame it before. Also, it tells you when to feed it at the bottom corner of your screen.
Everyone suggests breeding griffins to produce griffin Kibble for unicorns, but there's an alternative method.
You can use a TEK KIBBLE PROCESSOR, which utilizes one element per use. This device transforms the creature's implant (griffin implant) and a variable amount of Kibble (depending on the specific kibble type) into the same creature's Kibble as the implant.
You'll get only one griffin Kibble per use, so make sure to get as many griffin implants as you can.
