Based on the quotes and idle animations that Links does, it is known that he has dark paws, and that his paw-print is equivalent to his signature or approval stamp. Links is shown to need reading glasses (these are dark blue, and have a "Old Granny" style chains, also in dark blue), although he doesn't wear these to stamp documents; thus, it is assumed that he only needs them for small text. Links, based on his quotes, eats mice, and has an interest in playing the piano.
