Squibbles is a toy who first appears in "A Dragon's Best Friend." He appears as a yellow and orange ball of fuzz with blue antennae. He takes an immediate shine to Stuffy, but Stuffy is slow to warm up to him. He is a lost toy, but when Doc is unable to find his owner, Stuffy adopts him. Like other "toy pets" seen in the "Pet Vet" line, he can neither speak, nor understand speech.
