The Mandalorian has seen a number of protocol droids serve in inconsequential, one-off appearances, and while their presence is not at all uncommon in Star Wars, the most recent one in the employ of Greef Karga shows a clear behavioral distinction between them and the original droid, C-3PO. While almost all protocol droids share a common role as comic relief, Karga's droid exemplifies the more typical delivery of them being amusing through their socially oblivious nature, which creates a contrast to threepio, who was arguably the most talkative character of the original trilogy's entire cast. With every new protocol droid introduced, it makes it that much more clear how C-3PO's personality made him entirely different from the rest.
