Generally I will warn you not to get too excited when Fickle Pickle shows up on our list of plants. I will however point out that while they will not mass produce anything that we are looking for this week, they are your best source for Fossils and seem to supply them as one of their highest drops. Fickle Pickles are also the only plant that can provide both Fossil and Aether - and they can also give you Stone Block which you can Transmute into Fossil.
