Grinny Cat

By: Comickit

Dr.Goodworth opened the door to his lab and brought a few things through the door with him. A camera to record himself, a needle with a jar with a serum that he made himself, and his cat Oscar as his test subject. He set up the camera next to the table in the lab. He put Oscar on the table, grabbed a needle and filled it with the serum.

"Hello world you will probably view this when I'm famous! Now, you see this green stuff? This is my life's work! And this is our test subject: Oscar! This serum will enable animals to use and read human emotions!!" Dr.Goodworth picked up Oscar. "Well without further ado!" he said before he injected the serum into Oscar's chest. "ROOOOW!" yelled Oscar as the needle went into him. "Don't worry Oscar it'll only hurt for a second!" Dr.Goodworth put Oscar down to let the serum kick in. "Now ladies and gents, the serum is taking its effect to the cat's brain and corneas!" Oscar sat up after a while, his eyes were green before and now they are red. "Ah there we go, success!!! Oscar, could you please smile for the camera? The cat did so. "Well there you have it folks! We have taken the first leap into understanding our animal friends!" Dr.Goodworth. walked to his camera.

Unbeknownst to him, Oscar's smile was tuning into a demonic grin.

"Alright how do I turn this thing off..."

Oscar jumped off the table and started to creep towards Dr.Goodworth.

"Is it this button or do I just press this button again....." Suddenly Dr.Goodworth felt a bite on his leg. He looked down to see Oscar tearing apart his flesh, slowly. He fell to the ground screaming. Oscar crawled up to his face. "WHAT ARE YOU DOING OSCAR!" screamed the doctor before Oscar did something totally unexpected: he spoke. "I want your flesh and blood." the cat said before quickly bringing up his paw, drawing his claws and slamming down at Dr.Goodworth's neck.

Hours later a mysterious doctor walked through the corridor towards the lab. He was wearing a doctor's mask, goggles, a doctor's cap, and a lab coat. But he was wearing a pair of black pants and black shoes. The mysterious doctor walked down the hall to the door typed in the code and the machine responded "access granted welcome Dr.Goodworth". The doctor opened the door, turned on the lights, and shut the door behind him. He pulled off his doctor's mask and cap revealing the face of the most twisted mass murderer that the world has ever seen.

This killer was known as Jeff the Killer.

"Alright now where is that stuff Slendy wanted?" Jeff saw the dead doctor on the floor, And all the blood around him. "Whoa! It looks like someone beat me to it." He walked over to the camera in the room. He started to examine the camera, when he heard something coming from the corner of the room. "Mrrrow." Jeff turned to see a cat in the corner and it had blood all over its mouth. Jeff pulled out his knife for protection. "Oh so you're the little killer? You want to come with me little guy? I'm sure the Under Realm will suit you!" The cat walked slowly towards Jeff. "Mrow?" Jeff bent down and picked him up. "Come on then! You can live with me!"

As Jeff approached his home, he noticed something. "Oh my, your fur is falling out, it's ok, I'll call you Grinny because you remind me of Smile Dog."
