There is a “thing” on mobile solo where you leave the game and enter again, the Achatina will automatically have produced 100 organic Polymer. That’s 100 how’s of waiting turned to 10 seconds of leaving and rejoining. Everyone should take advantage of this “thing”
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.
