It was an average day at the circus. The ring master was teaching the new recruit how to juggle various fruits, the lion tamer was teaching his lion NOT to bite off fingers, the twins were practicing on the trapeze, and the rest of the staff were hard at work, preparing for the next performance.
But this all changed when they came across a strange goo-like substance. When it came into contact with flesh, it seemed to weld onto its new host. It would then control said person, and act like a sentient parasite.
The first person to come into contact was Carl. His clown wig kept sliding off of his head, and he needed it to stay in place until he took his makeup off at the end of the day.
He was quite nervous, because the performance would start soon. He thought that the goo might help it stick to his head, so he didn't hesitate. However-he did not appear at the performance. He stumbled down countless streets, not stopping for anything.
He still walks to this day, aimlessly walking by countless pedestrians.
