I picked up a “snail” in the redwoods with my “pterodactyl”, and dropped it in my base (surrounded by spike walls). It wondered around and dropped cement paste for a while, but it kept trying (unsuccessfully) to escape... so I built a wooden platform with 3 window walls and a door, & dropped it in with my “pterodactyl”. I could stand outside the window and grab the cement paste before I was able to tame it (with 10 cakes). Very handy companion. I’m trying to make a tree platform and you need like 1,000,000,000 cement paste to do it...
Achatina
The Achatina is a massive snail, mostly used for its production of Cementing Paste, or as a pet. This creature produces its paste passively — and quite frequently — so many survivors keep them around their bases. However, its usefulness pretty much ends there, as it cannot attack and moves quite slow. The Achatina must be tamed violently.

Knockout and then but veggie cakes in it inventory and yeah pretty simple
They can wear hats!!!
If you are considering breeding these, go slam your hand in a car door a few times. It will be much less painful. Literally one veggie cake per percent of growth....and it grows slow.. Digests roughly one point of food per second, so feed a cake about one for every 7 mins…

Digests roughly one point of food per second, so feed a cake about one for every 7 mins (during event boost) and it will gain one percent of growth.
Do not starve tame. There is a cool down on the veggie cakes that don't allow it to eat them as quickly as needed.
It shits cementing paste
If you are playing Official PvE, you can grapple them with a grappling hook and then fly or walk them back somewhere safer for them to be knocked out, such as your base for example.
I like to make note that this is a knock out tame
U CAN GET CAKES THROUGH CHEF STATION ON MOBILE!
