The cyclops dog is a minor character in The Amazing World of Gumball. It is briefly seen in "The Dress," when Gumball is coming up with a fake name. It is also seen in an Australian promo where Mr. Small drops its leash in surprise and in the background in Splash Master. Based on its appearances, it seems like Gary is the dog's owner.
The cyclops dog is a small, quadrupedal dog-like animal. It has turquoise fur, a large green eye, long, rabbit-like ears, small stubby legs, and a short tail.
The cyclops dog has been seen fitting an entire soccer ball in its mouth, perhaps signifying an unusual appetite.
