Chip is the logical schemer, and Dale is the goofy, dim-witted one. Originally the two were of a very similar appearance, but as a way to tell them apart, some differences were introduced. An easy way to visually tell them apart is that Chip has a small black nose (it looks a bit like a chocolate "Chip" as a way to help people remember who is who) and two centered protruding teeth, whereas Dale has a big red nose and his two prominent buck teeth exposed. Chip is also depicted as having smooth, short fur atop his head while Dale's tends to be ruffled.
