I've talked to Jackie and she says the GenPearls were purchased as starters from the store. Calculation shows this to have been on April 12th 2020. Which is well after the Love Collection, but who knows if the trait was loaded into Starters separately? It is, of course, after the Foolins and the fur was seen on a Foolin. So the question is.. did this and other new traits get loaded in at the time of the Foolins.
