A wierd idea i though of for a probably dumb crossover story. it's a combination of the subspace emissary + jsab story mode + other stories like it. This scene would happen before a boss fight. Where meat boy, bandage girl and Elma escape the halls of the Hospital-turned-lab, but Dr. Fetus got the jump on them, preparing to unleash one of the Experiments that was created here.

Meat boy and Bandage girl and Dr. Fetus are from @BlueBaby (Aka Edmund McMillen)
