The Berry slime is a rather unlucky slime. It is smaller than other Slimes and often mistaken for a fruit. You will need to keep it separated if you don't want them eaten.
Eating a Berry Slime is not treated as eating another Slime's plort, However it is treated as a fruit and can be used as a food source. But who would be so cruel to do such a thing?
