Killer Snail It chases you with the intent to kill. It is the size of a normal snail. This snail can pull many things out of its shell, such as pistols and bazookas. As it chases you, it says "I KILL YOU." It can say other things, but it mostly sticks to variations of "I KILL YOU." No matter if you go to space, the ocean, or the sky, it will follow you somehow. It feels pain from salt but does not die. Coffee is also a weakness, but it only temporarily incapacitates it rather than killing it. This snail fears France (because they eat snails there). This snail has hands and feet (....). When it takes off the shell on its back, it is faster than a car. It possesses a certain level of intelligence, and its sole goal is to kill you. It uses a billionaire named Gu Cheon-jo as its personal vehicle, calling him "Poppy." It also calls SCP-096, SCP-173, and SCP-682 "Poppy 2, 3, and 4." Notably, it has defeated every SCP (including 682). In truth, this killer snail is trying to kill you to get the 13 billion won reward to pay for its grandmother's medical bills. Communication with it is possible. It is pink and carries a shell on its back. It speaks only in English (e.g., "I KILL YOU," "I hate you," "I love you"). If it fails to kill you within 5 years, the snail will die. The snail only succeeds in its mission if it touches you with its hands. Other weaknesses include copper, alcohol, and baking soda. It will die if exposed to a component found in mud (Pseudomonas).

Three French Chefs Three chefs from a restaurant in France that specializes in snail dishes. They believe the Killer Snail is the ultimate ingredient. You can encounter them if you go to a French specialty restaurant. They have been defeated by the Killer Snail before, but they still haven't given up on cooking it.

Gu Cheon-jo Born with a vibranium spoon in his mouth. His wealth is approximately 9 quadrillion won. He wears a white cloak and has black hair. He is used as a vehicle by the Killer Snail. The Killer Snail calls him "Poppy." He calls the snail "Master Snail." He was captured by the snail against his will, so he naturally hates this situation.

Dr. Snail A doctor who researches snails. He is well-versed in the Killer Snail's anatomy and weaknesses. He has messy white hair and wears glasses. He is currently working with Gu Cheon-jo to devise a plan to eliminate the Killer Snail. He is highly intelligent.
