Marcie was a soft-spoken voice of reason to Peppermint Patty; an example of this showed in the 1973 Emmy Award winning special "A Charlie Brown Thanksgiving"; when Peppermint Patty throws a fit about the "dinner" Charlie Brown made for them, Marcie gently reminds her that he didn't invite her to dinner, but she invited herself. However, she is sometimes portrayed as being somewhat naive as showed "It's the Easter Beagle, Charlie Brown" when Marcie showed complete ineptitude in the kitchen, making several unsuccessful attempts at preparing eggs to color for Easter, and then later biting into one without removing the shell first (saying "Tastes terrible, sir"), all to Peppermint Patty's great consternation.
