if you want a lot of cementing paste but don't have veggie cakes, call up your argeventis and swing by the swamp. use the argy to pick up a wild achatina and carry it home. drop it into an enclosure and boom! free paste, no taming required. just make sure nothing gets in and kills it
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 (during event boost) and it will gain one percent of growth.
