Snuffy is a small green monoplane. He Is equipped for skywriting. In episode's consistency (which depends on the order), one episode says he has not flown further away from Tarrytown than Lightning Bug Lake, but other episodes show him fly much further; In Gumpy O'Malley, it's revealed he gets shy easily, but in many other episodes he shows no sign of shyness.
Snuffy is the youngest plane of the group and his specialty is skywriting. He's always plagued with sniffles (sometimes from all the smoke that he produces) and when he speaks, he sounds stuffed-up. But even so, the gentle warmth and compassion in his heart always come through. And since Snuffy is experiencing most things for the first time, he's a little cautious and sometimes his fear of new things gets the best of him. But, he manages to overcome his fears and move forward to the next challenge. When Debi Derryberry joined the series when Snuffy didn't know something he asked Jay Jay and Jay Jay would describe the thing to him.
Snuffy is a cute skywriting monoplane who is light pale-skinned, has medium blue eyes and buck teeth. He is painted yellow-green with yellow patches on either side, and thin yellow stripes on his landing gear. His propeller is wooden with a red center. His wheels are black with dark grey hubcaps.
