Tips & Strategies

They forgot one thing, you can harvest angler gel from these guy. Which are used to tame manta ray, I've got thirty-one at least if not more. Also you don't have to tame it to receive cement paste, just follow it around or use a Ptera and bring it back to your base and collect it there. I'm also on Ark mobile.
More Achatina Utility Tips
Just tame 5 or 10 of these and put inside them a lot of Stone or something heavy so they cannot move when you put them into patrol. With that, they passively generated 100 achatina paste every hour. When you don't take those achatina paste, they start to generate organic Polymer. Just make sure those snaila cannot move and you have a nice auto-paste farming.
TIPP: Achatinas can produce organic Polymer. You can just craft a fridge with the organic Polymer and destroy it. Every time you destroy a fridge you get normal Polymer back. That means you can transform organic Polymer to normal Polymer. I found it out yesterday by myself.
(It also works with organic Oil)
