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.
