Plop it at your base and then somehow aquire a personal honey bee hive for veggie cakes. Great for polymer and cementing paste. Upgrade their food bar whenever it gets enough exp. So then it can go a lot longer without food, and wont die as fast from starvation. I can play for like three days and then decide whether or not I want to top up its food bar.
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.
True story. We tamed 6 achitnas for cementing paste and polymer farming. Their pen is near our ovirapter who is weighted down and set on wander. These snails reproduced. We returned from an adventure and found 6 mini me's! We separated the achitnas into pens divided with wooden rails and they still reproduced. Not one was set to "enable mating". We finally spayed all of them to get them to stop! If you want organic polymer (store on the achitnas) and cementing paste you will have more than enough in no time. Spare the baby penguins!
