It had been three days since SpongeBob realized he was a monster. Three more people had mysteriously vanished since the first one was found dead. Only SpongeBob had an idea on where they were. No matter what he did, he couldn't control himself. Every night that strange sensation came over him and it was like he was no longer in control of his body. Even his mind would work against him. It was now five in the afternoon. One more hour and it would happen. He was preparing to lock himself in the library when there was a sudden knock at the door.

"SpongeBob, are ya'll home?"

"Sandy! What are you doing here?" He ran over to the door and flung it open.

"Howdy SpongeBob! Me and Patrick just stopped by to make sure you're all right. Ya'll haven't been acting like yourself lately." SpongeBob looked past Sandy and noticed Patrick standing behind her. He waved to him and SpongeBob nodded his head in return.

"Uh well you guys really shouldn't be here." He glanced back at the clock. It was 5:23."

"Well then I'm heading home. It's almost Mermaid Man and Barnacle Boy time!" Patrick raced off towards his rock and belly flopped right into his chair. He turned on the T.V. and started laughing. Then his rock slammed shut leaving SpongeBob and Sandy standing in SpongeBob's doorway.

"So are you gonna let me in or what?" Sandy put her hands on her hips and looked at SpongeBob. He looked up at her and let out a big sigh. He knew better than to argue with Sandy Cheeks. So instead of saying anything he just simply stepped to the side. Sandy smiled and walked past him. Once they were both inside, she turned back to him.

"Look SpongeBob. I know something's wrong with you. Are you sick?"

"Well not exactly. It's just…" he looked up into her concerned eyes, "really hard to explain."

"You know you can tell me anything SpongeBob."

"I know Sandy but… I…" He looked back over at the clock. 5:32. He needed to get Sandy out before it was too late. He looked around and stared towards his library. With a shock he realized that it locked from outside. "Uh Sandy, I need you to do something for me."

Ten minutes later Sandy was locking the library door while SpongeBob tried his best to explain why she needed to do that, from the other side of the door.

"I still don't get why you want me to do this SpongeBob."

"You just have to! I can't really explain it right now. What time is it?"

It's… 5:45, why?"

"Sandy you need to get out of here. Just come back tomorrow morning and open the door after its already bright outside. Ok?"

"I'm not leavin' y'all by your lonesome self SpongeBob. What if there's an emergency?"

"No Sandy! You have to go! If you don't your life will be at risk." The other side of the door was quiet for a minute. SpongeBob thought that maybe he had scared her away and started to feel relieved. Then she spoke up again.

"I don't care SpongeBob. I'm not leavin' you."

"Alright Sandy fine. You can stay just… whatever you do don't let me out of here. No matter how much I beg. Do you promise?"

"Yea, sure. I promise." Just then the clock began to chime. It stopped when it reached six. From inside the library, Sandy could hear loud moaning. Then everything went eerily quiet. "SpongeBob, you alright in there?"

"Yes Sandy, I'm perfectly fine." She jumped back away from the door. She could tell by his voice that he was speaking into the crack. But that wasn't what scared her. There was something about his voice. It was darker and deeper than normal. And his tone sounded, well, she couldn't describe it. "Why don't you let me out of here Sandy?"

"But you told me– "

"I know what I told you!" SpongeBob snapped at her. "I mean, I'm hungry Sandy. Couldn't I just come out for a bite?" He tried to calm his voice down but he still sounded like he was speaking through gritted teeth.

"I'm not letting you out SpongeBob!"

"Fine Sandy! I don't need your help anyways!" He snapped again. There was a couple moments of silence. The all the sudden there was a huge crash. And silence again.

"SpongeBob!?" But there was no answer. Sandy pulled open the door and gasped. In the back of the room was a decent sized hole in the middle of the wall. She had no idea SpongeBob was so strong. She was still taking it all in when the creaked open and slammed shut. She jerked around but no one was there. She had a strange feeling that she wasn't alone anymore. Her heart started beating faster and she slowly spun around in a circle surveying the room. Her senses started reeling and her head shot up at the ceiling. To her terror, SpongeBob was clutched to the ceiling right above her. He gave her a gruesome smile and dropped down in front of her. That's when she noticed the long, sharp teeth. Chills shot down her back and she could feel her fur standing on end. There were other things different about him too. His eyes were red and blood shot. He was a darker shade of yellow and seemed to be bigger somehow.

"Will you join me Sandy?" He held out his hand to her like a true gentleman would. She wanted to swat it away but was too scared to move. Instead she swallowed and shook her head. "You have a choice. You can join me, or you can join those other four in their graves." A small tear slid down Sandy's cheek. Just for a second she thought she could see SpongeBob's eyes flash blue and his face was concerned. But he winced. When he looked back up, he was back to his vampire self. He gave her another evil smile. "Come Sandy." He stepped to the side indicating for her to walk in front of him. She glanced back at the wall behind her and knew there was no point in trying to fight him. He could easily kill her. She swallowed again and started walking. What was he planning on doing with her?
