Lobit tries to hack them like the prototype Toy Bonnie, and ends up making some errors because of the amount of agony that was in the place because it was exactly where it all started (Fredbears familly dinner It's the place where FNAF 6 takes place) And with this agony, together with the advanced A.I that Lolbit created in them with her virus, it generated this slightly realistic but still somewhat neutral personality of theirs.

They want revenge because they took the agony of Cassy who died at Fredbears in Golden
