Easy to tame and worth doing so. Each one produces 1 paste a minute (level doesn’t matter so go for the lower ones) and carries a max stack of 100 paste. Only eats cake, even after tamed but the foot goes down real slow so it’s not too much of a bother. Once the paste is full it then starts producing organic polymer at a rate of 1 every 60minutes. However, they spoil every 1 1/2 hours so you don’t really see it.
You mostly find them in caves, near mountains and also near swamp regions. They can’t really run away from you but taking them isn’t that easy either and might take a little more resources than you think at first but if you are far and rather prepared in the game this should be no problem. If you take them and put them on „wandering“ they will „snail“ around and slowly produce up to 100 Achatina Paste and 3-5 Organic Polymer if you leave them alone for a while. A simple short exploration is enough for these bad boys to generate a lot of Paste.
