The Blob

Classroom outcasts Shin-su and Jin-o were forced to eat Physarum Polycephalum because of school bullies.

The two outcasts, who are still bullied and ignored at school, gradually take over the food chain while keeping their identities a secret. However, as the slime traces start to surface one by one, they start to cause social problems, and the fight intensifies when Kim Soo-hyuk, who created a mutated blob experiment, appears.
