Ballon Dogs are about the size of a dog, completely black, with a round, big torso. Their heads are barely half the size of a normal dog’s and hang so low that they almost touch the ground. If they get mad, their bodies swell up like a balloon to warn their enemies to stay away. But if provoked even more, they puff up bigger and bigger until they finally explode. When they blow up, the enemy will likely be killed, or at least seriously injured.[1]
