[Sweet! Thanks.]
666 woke up in a cage with a grouchy blink, pacing before the scientists grabbed his cage and took it over to a table. They injected an absolutely PLEASANT liquid into his flesh, and soon he experienced nausea and pain in one of his lungs. The scientists continued injecting things into him, giving him cancers and such, and some of the formulas healed the various symptoms of the experiments. "Hey. Hey. Hey. Hey. Hey." A hyperactive, long-tailed black chihuahua in a cage nextdoor barked to him. "Ya gotta kill me, bro. I ain't gonna die on m'own." It complained. 666 sighed, white fur getting more matted. A scientist brushed it through and through to get the mattedness out, but that was it. He groaned and bonked his face over and over into the cage door. A boxer whose breed was barely recognizable sat across the room, head up and one of his eyes staring down at him. "SOON..." It barked, minimized ears and long-as-heck tail set pointing towards the wall. It also had ridiculously long legs, and it seemed rather underfed and lean. Its face was wrinkled and flat, but its head was ridiculously long anyways. Overall, the creature looked... RIDICULOUS. He shook his head, its asymmetrical leg lengths(His left leg was ridiculously long, but the right was normal length) irritated him. 666 groaned, turning around. The scientists soon put him away, and the next morning he'd be injected with more fluids. Lots would give cancers, some would heal them. One even made him seem even more demonic, lengthening his teeth and making his personality even worse. And the very next syringe got rid of that. He'd be put away so he could nap, and he'd end up sleeping for a long time.
[Sorry about how long that was v_v]
