Ark mobile is for kids that can’t hack it with the big dogs in REAL ark. I’m sorry if it hurts your lil tiny feelings but it’s true. Stop playing that garbage knock off and play ark for real where everything isn’t super easy and handed to you without having to work for it or spend your money to revive your lil parasaur
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.
