Velma has been called in to consult on an unexplained crime scene: a person has vanished into thin air, the house is immaculate, and the neighbors have only heard a suspicious *pop* on the night of the disappearance. The girl wanders around the house looking for clues: she approaches an overturned cup with whitish liquid spilled on the table. Inexplicably, Velma is driven by a mysterious fascination to dip her fingers in it and bring it to her mouth.. after doing this several times, the girl comes to her senses and creates a sample to send to the lab. Hopefully no one notices her lack of professionalism! And let's also hope that that liquid isn't dangerous.. she swallowed way too much of it! Velma reports back, fortunately no one has noticed what she has done.. when suddenly, the girl's abdomen starts to be filled with very painful and noisy spasms. The pain increases with every passing moment and her stomach starts to.. grow?! tearing her shirt! Velma realizes the way the person disappeared.. the mysterious liquid, the belly about to explode, the mysterious *pop*.. it all comes back! The case is solved! Too bad Velma can't be happy about it because her belly reaches its limit and explodes!
