Putting your own safety aside, you rush to the man's aid. Just as the beast begins to sink its teeth into his shoulder, causing his screams of terror to turn to screams of agony, you tackle it as hard as you can. It flies off of him, the squeaks of its body movements mixing with canine squeals of pain, and it slinks back into the shadows as it realizes that its victim is no longer alone.
You kneel down to the man to make sure he's okay. He's unconscious, but he's still breathing and surprisingly there's no blood. You look for bite marks, but where you'd expect to see puncture marks there are small purple dots. Confused, you look closer. From what you can tell, those dots are made of the same substance as that wolf creature's skin... and you soon realize that they're spreading.
Within a minute, the small dots have quickly become a large patch of purple latex covering his entire shoulder and working its way down his arm and across his chest. Apparently, that thing is contagious.
