Ultimate Mobile Edition:

Info-On Ultimate Mobile Edition the Unicorn poops like any other dino, no rainbow poo, no special effects. Also you can tame it with crops like the Equus. Highly recommend using Simple Kibble instead of crops, also on single player if your percentage for taming goes down (effectiveness and taming bar) knocking it out will reset it. Just make sure to let its health go back up completely before trying again or else its health might go down and both the taming and effectiveness will go down.

Taming-Full Ghillie and Simple Kibble are highly recommend rather than crops.

Trap- acquire a tamed Argy and pick it up, drop it in a two by two or a one by two foundation with doorframes all around recommend one high. And add ramp on one of the doorframes to get above it and feed it without it noticing you. Knock it out to reset its taming effectiveness.

Trap 2- bola it, knock it out, use the first dino gateway available, with the doors, three of them in a triangle with a gap. Don’t forget to make sure that the gap isn’t too big or else it will be able to get out.

Extra-will typically spawn in the same areas as Ovis (yes it exists on the ultimate mobile edition- aggressive dinos will target it over you so if you see one grab it immediately, its health is low and runs like any passive runner) and Equus. On the Dododex look at maps the map your on, ARK: Survival Evolved, click on creatures, type in Equus, Ovis or Unicorn. If it dies leave the area and look in another spawning area, if there’s an Ovis or group of Equus in the area it won’t spawn in within the area. So kill them or tame them and lead them out of the area (far enough that it renders out other dinos and make sure that at least five minutes pass before trying that specific area again). If you tame one it will respawn in another spawning area so if you want a breeding pair it’s possible.
