One of the best ways by far to collect paste if you use the S+ mod. Tame a ton of them (12 is how many I have. It’s a little much...). Use the S+ Collector to passively collect their pasty poop, and regularly pull all their inventories. To keep them fed, use an S+ Tek Feeding Trough and set it so that only Achatina’s will eat from it and fill it with cake.
I don’t worry about paste now. Day 780 something on the server and have a surplus of about 80,000. This method is ideal with S+ (as most of us use it). However, regularly checking their inventories will also yield more than you’ll need.
When tamed, the Achatina can produce Achatina paste, an alternative to cementing paste, passively when on wandering. You could also collect it when they are moving, their paste/slime will be on the ground shaped in a similar feces ball.
Will only eat Sweet Veggie Cakes even after being tamed! Each cake fills the food by about 200. Poops paste as well as prudces paste in inventory but ceases production once 100 paste is in inventory. Increases organic polymer spoil timer by 3x
1. x3 organic polymer spoil timer
2. Passively produces organic polymer and cementing paste when wandering
3. Poops Cementing paste, even while still, but if still, you must move the achatina to see the paste
