Oviraptor Kibble (MOBILE) is used to tame the Megalosaurus.To make Oviraptor Kibble (MOBILE), combine Oviraptor Egg, Longrass, Prime Meat Jerky, Mejoberry, Fiber, and Waterskin in a Cooking Pot. Start the fire and cook for 30 seconds. It spoils in 3 days.
To the person who said oviraptors won't let you get away, THEY run away from YOU not the other way around. Stealing the egg is a piece of cake and extremely easy as they spawn everywhere. Hope this helps someone!
