This is for Pickles the species. See The Mighty Pickle for him.
Then I shall bring corruption into your world. No longer will the sun shine, no longer will the ducks quack. There shall be no joy, no laughter, no happiness. Your world shall become miserable...
Sentient Pickles are merely pickles brought to life through evil magic by either Piqlantists or The Mighty Pickle himself. While they have some traits that make them look similar to the primordial versions, they are nothing more than giant (or regular-sized) pickles brought to life.
Regular pickles are just that. They can be used as magic tools, but most of the rumors of them being evil artifacts was superstitious nonsense. If anything, The Great Duck just dislikes the taste (and smell) of pickles. Some pickles are actually eggs of primordial pickles; however, very few of them remain.
