The Penny Pincher is the only cog with red colored hands, with an exception on the Money Bags trading card.
Likewise, they are the only Cogs with red skin.
The trading card shows it attempting to steal a Toon's piggy bank.
Illustrations of them on Toontown related merchandise often depict them as having pincers for hands (due to their namesake) but in the game itself, they have normal fingers and hands. In fact, its finger is pretty much the main event when it uses its "finger wag" move. It does, however, appear to have a coin slot on the tip of its head, as if it is a money box (or a piggy bank), which fits the name.
