Gordon has mostly white fur with an orange/ginger spot around his left eye that resembles a bicolor cat.

He has a stumpy orange tail and a pair of green (or in earlier cases, blue) eyes with black pupils.

He has no nose, has five orange hairs sticking out from his chest, a wide mouth with sharp, yellow-ish teeth, and mostly resembles a big bag of flour.
All honor and heart, righter of wrong, do-er of good, Gordon is a sloppy bachelor who harbors a less-than-secret crush on the girl next door.
