Scrambling on the ground, you're able to take a hold of the gun. Spinning around, open fire on the guards. In the time it took for you to grab the weapon, Tom had already leaped across the room and tore another guard apart. Most of the staff present had fled the area, excluding one who was cut off from the hail of bullets and the creature. His only chance was the English Werewolf Exhibit door, which was not opening for him. Even the guard who owned the gun you held had now fled.
The bullets lodging themselves into Tom's massive bulk was slowing him down. As strong as he was, the weapons appeared to be doing the trick. With a glance to the side, you could see the remains of a few of the bullets that had missed. They were definitely silver.
However, the guards were too distracted by the beast to notice you arming yourself. You're able to take down the last of the guards without much trouble, quickening Tom's work. As the last armed guard fell, Tom lunged at the final guard in the room, the one screaming through the English Werewolf Exhibit door to be let in. The man didn't have a chance to even cry in pain.
After a loud crunch from his teeth, the large bleeding creature turns its attentions on you. Unnervingly, the inhuman mouth gives a wide smile. "Well, well, well," he says in a voice deep and cruel. "An appetizer comes to help aid the diner. How quaint." As he takes a few steps towards you, an alarm siren goes off throughout the zoo. "Looks like I'll have to make this quick."
Stepping back away from him, you try to raise your gun. "Listen. I-." The creature grabs your hand, and the last bullet is fired. It pierces Tom's hand as he winces in pain. But it barely slows him down as his hot humid breath bares down on you. Surprisingly it takes a few moments before you truly feel the pain of your flesh being ripped away from your throat and chest. Your limbs begin to twitch rather than obey the commands you tell them.
"Hello," called out the woman from inside the box. "Is anyone there?"
Tom ignored her as he ate. And as Tom slowed down in his bites, you realize that the bullet wounds are killing him. Unfortunately, it wasn't fast enough. Your body wasn't even going to have a chance to nourish him.
Your last thought is that was at least something.
