Beak and Muzzle Characters

the characters im thinking of using for my beak and muzzle character assignment, 2 elderly characters that are best of friends, the dog is grumpy about everything and uses a cane with a tennis ball at the bottom for grip, and the other is very optimistic bird with a branch for a cane, the bird brings up great times from the past, and the dog just complains about how horrible those days were...
